Sonde Install / Replace EXO1 Batteries EXO1 water quality sondes use two (2) D-cell batteries as a power source. Using alkaline batteries, users can expect approximately 90 days of deployment from a fully loaded sonde that samples once every 15 minutes. However, deployment times may vary greatly depending on water temperature, sampling rate, sensor payload, and brand of battery.
Page 26: Replace Battery Cover
4 Check and service o-rings NOTE: Before replacing the battery cover, check and service the four o-rings. Ensure that the o-rings are not nicked or torn and that there are no contaminants or particles on them or the sealing surfaces inside the battery cover. Clean the o-rings with a lint-free cloth.
Page 27 EXO3 sondes use two (2) D-cell batteries as a power source and can expect 60 days of deployment with an average sensor payload while sampling once every 15 minutes. NOTICE: Do not use Ni-Cad or 3.6 V Lithium batteries in the EXO sondes. Pressure in Battery Compartment The EXO2 and EXO3 sondes are equipped with a pressure relief valve to protect against catastrophic battery failure.
Page 28 3 Insert new batteries With the positive terminal facing up, insert four (4) new D-cell batteries into the battery well for EXO2 sondes, or two (2) new D-cell batteries for EXO3 sondes. Tilt the sonde horizontally and gently slide the batteries into the sonde to avoid damaging the batteries or the battery terminal.
Page 29: Install / Remove Guard Or Cal Cup
Install / Remove Guard or Cal Cup Sensor guards protect EXO sensors from impact throughout deployment. Users must install the guard prior to data collection. The calibration cup (cal cup) is used for storage and calibration. NOTE: We recommend using two sensor guards and two calibration cups: one for field deployments and a second used exclusively for calibrations.
Page 30: Install / Remove Sensors
Watch Now EXO sensors have identical connectors and identify themselves via onboard firmware; therefore, users can install any probe into any universal sonde port. The exception is the wiper for the EXO2 and EXO3 sondes, which must be installed in the central port 7.
Page 31: Sonde States And Led Descriptions
When Off, the sonde is not powered (no batteries installed, no topside power) and cannot collect data. Users can apply power to the sonde internally, using batteries, or externally with an EXO field cable attached from the topside port to an EXO Handheld, DCP or other approved power source.

Page 57: Daisy Chaining Sonde Expansion
Auxiliary Port 3 Connect Sondes to SOA-DCP Using a flying lead cable, connect the topmost sonde to an EXO DCP Signal Output Adapter. Install batteries in the sonde furthest from the DCP adapter first. Then install 6-Pin batteries in the next sonde furthest from the adapter and then the sonde closest to Cable the adapter if there are three sondes attached.
Page 58: Sonde Clamping / Mooring Long-Term Monitoring
In long-term monitoring applications, where the sonde will be left unattended for long periods of time, it is critical that you properly mount and protect your EXO sonde. This will ensure you receive quality data and that your instrument is not lost in a flood or other natural event.
Page 59 Horizontal Deployment Tube In shallow water applications it is possible to deploy your EXO sonde horizontally. However, care must be taken that the sensors stay submerged and hydrated. This configuration has inherent risks such as sediment build up and is somewhat susceptible to flooding events even when properly fixed in place.
Page 60 Sonde Clamping Guide Great care should be taken when securing an EXO sonde to other objects. The preference is to deploy the sonde inside of a PVC pipe without clamps as described previously. However, if clamping is desired, the sonde should never be mounted directly to a mooring line, steel cable or piling as the pressure from a band clamp will deform the sonde and potentially cause leaks.

Page 64: Instrument Connection Panel
Wired Connection: There are a few ways to establish a wired connection to an EXO Sonde. The most common method involves using a USB Signal Output Adapter (SOA) which plugs into the sonde directly. Alternatively, one can use the EXO Handheld or EXO GO which connects to the sonde via a field cable and connects to the computer via a USB cable.
Page 65: Wireless Connection
Wireless Connection: Every EXO Sonde includes a built-in Bluetooth chip which allows for wireless communication with a computer or mobile device that has Bluetooth capabilities. This is extremely convenient for calibration and sampling at the surface level. However, the Bluetooth communication is severed when the sonde is submerged under water.

Page 123: Data Filtering
EXO sondes collect data from the EXO sensors and are able to output data at rates up to 4 Hz.
Page 124: Adaptive Filtering
Response times for EXO sensors are based on laboratory testing. This testing, though stringent, cannot mimic the actual response times in the field due to the wide variety of use cases. To characterize an EXO sensor’s response time, a step change in the sensor’s primary output parameter is applied, and the time to reach 63% of the final stimulus value is recorded.
Page 125: Basic Overview
Watch Videos Now Basic Overview EXO sensors (except temperature) require periodic calibration to assure high performance. Calibration procedures follow the same basic steps with slight variations for particular parameters. Calibration procedures described in this section will mainly focus on using Kor Software. Refer to Section 7.4...
Page 126 Factory Reset Calibration A Factory Reset Calibration can be performed to return the sensor gain and offset to factory specifications. Performing a Factory Reset Calibration will allow the user to start a calibration with default sensor metadata values. A new calibration of the sensor will then help with additional troubleshooting, if needed.

QC Score. Calibration Reports are saved in the Kor Software database on the computer or the EXO Handheld that was used during calibration (not on the sonde or the sensors). All reports can be accessed and viewed through the Calibration Records menu in Kor Software.
Page 128 Every EXO sensor has an embedded microprocessor which, along with calibration metadata, enables EXO to warn users of calibration errors or when a sensor is unable to be calibrated due to age, fouling, or damage, for example. For any sensor a QC Score is presented as red, yellow, or green: A green SmartQC Score means the sensor is calibrated properly and all parameters used to assess its performance state are within factory-defined limits.
Page 129: Sensor Overview
Sensor Overview The EXO combination conductivity and temperature sensor should be installed in nearly all sonde applications. Not only will this sensor provide the most accurate and fastest response temperature data, but it will also provide the best data for the use in temperature compensation for the other EXO probes.
Page 130: Temperature Thermistor
EXO sensors reference the C/T probe for temperature compensation. To display and log temperature, a C/T probe must be installed in an EXO sonde. Thermistor readings are logged in the sonde’s raw data–viewable in Kor Software–...
Page 131 1 mS/cm (1000 μS/cm) for greatest stability. Pour conductivity standard into a clean and dry or pre-rinsed EXO calibration cup. YSI recommends filling the calibration cup up to the second marked line to ensure the standard is above the vent holes on the conductivity sensor. Immerse the probe end of the sonde into the solution, gently rotate and/or move the sonde up and down to remove any bubbles from the conductivity cell.
Page 132 An ideal cell constant is dependent upon the type of conductivity sensor; there are two types of conductivity sensors (wiped and non-wiped) on the EXO platform: • For non-wiped conductivity [599870], the ideal cell constant = 5.1/cm ± 10% The CT sensor can be evaluated in air when it is new, and as the sensor ages this may be a useful tool for assessing its drift from factory performance.
Page 133 Biofilms, barnacles, and algal growth are common culprits of poor data quality, clogging up conductivity cells and coating sensor optics. While the EXO Central Wiper can mechanically remove biofouling from other sensors to maintain data integrity over long deployment periods, in particularly high fouling environments the EXO Wiped C/T sensor provides superior conductivity data by avoiding stagnant readings and reducing the impact of micro-environments.
Page 134: Sensor Installation
Sensor Installation EXO sensors can be installed in any port, however for optimal cleaning avoid installing the Wiped C/T sensor as the first or last sensor in a group. If two conductivity sensors are installed in a single sonde, the temperature from the sensor with the lower port will be used for temperature compensation of other parameters.
Page 135 An ideal cell constant is dependent upon the type of conductivity sensor; there are two types of conductivity sensors (wiped and non-wiped) on the EXO platform: • For wiped conductivity [599827], the ideal cell constant = 0.469/cm ± 0.05 Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: Gain is within acceptable limits.
Page 136 “zeros” the sensor with respect to the local barometric pressure. A change in barometric pressure will result in a zero shift unless the transducer is recalibrated to the new pressure. EXO sondes have intake openings to allow water to act on the strain gauge. The EXO1 and EXO1 intake is located above the label of the sonde.
Page 137 Depth and Level 5.10 Calibration NOTE: This calibration option is available only if your sonde is equipped with an integral depth sensor or a vented level sensor. For the calibration, make certain that the depth sensor or vented level sensor is in air and not immersed in any solution. Also, review the basic calibration description in Section 5.2.
Page 138 SmartQC for Depth The SmartQC Score for depth and vented level is based upon an expected offset that would be computed by the sensor at the time of calibration. Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: The offset computed during the calibration is within factory specified limits.
Page 139: Dissolved Oxygen
The principle of operation of the EXO Optical Dissolved Oxygen sensor is based on the well-documented concept that dissolved oxygen quenches both the intensity and the lifetime of the luminescence associated with a carefully chosen chemical dye. The EXO DO sensor operates by shining a blue light of the proper wavelength on this luminescent dye which is immobilized in a matrix and formed into a disk.
Page 140 Variables that Affect DO Measurements Variables that could affect dissolved oxygen measurements include temperature, salinity, and barometric pressure. Temperature and salinity are compensated for during instrument calibration and field use with real-time readings from the EXO Conductivity/ Temperature sensor and/or instrument software settings.
Page 141 In the Calibrate menu, select ODO, then select ODO % Sat or ODO % local (% CB or % RTB.) Calibrating in ODO % Sat automatically calibrates ODO mg/L and ODO % local and vice versa. NOTE: ODO % RTB is only available when the sonde is connected to the EXO Handheld or EXO GO. The barometric pressure will automatically populate in the calibration window.
Page 142 NOTE: Carrying out DO mg/L calibrations at values outside the range of ±10 % of air saturation is likely to compromise the accuracy specification of the EXO sensor. For highest accuracy, calibrate in % saturation. Rinse the sonde and sensor(s) in tap or purified water and dry.
Page 143 Dissolved Oxygen (DO) calculations are derived from polynomial equations based on the K1-K7 coefficients that are provided with each new EXO Dissolved Oxygen sensor cap. Each sensor has been thoroughly tested during the production process to generate these unique calibration coefficients.
Page 144 Red: The gain or zero-DO calibration coefficient has drifted significantly from the factory specified limits and the sensor may not report correct values. If a user calibration results in a red QC Score, perform the following actions: 1. Thoroughly clean the sensor and ensure that all debris is removed from the surfaces of the sensor. Occasionally, thin films from sediment may affix to the lens cap surface and will affect readings and calibrations.
Page 145 5.13 Sensor Overview The EXO fDOM (Fluorescent Dissolved Organic Matter) sensor detects the fluorescent component of DOM (Dissolved Organic Matter) when exposed to near-ultraviolet (UV) light. Colored Dissolved Organic Matter Users might wish to quantify colored dissolved organic matter (CDOM) in order to determine the amount of light which is absorbed by stained water and thus is not available for photosynthesis.
Page 146: Calibration Standards
Remember that only trained personnel should handle chemicals. Preparation Use the following procedure to prepare a 300 μg/L solution of quinine sulfate (300 QSU) that can be used to calibrate the EXO fDOM sensor for field use: 1. Purchase solid quinine sulfate dihydrate (CAS# 6119-70-6) with a high purity (>99%).
Page 147 fDOM 5.15 Calibration Review the basic calibration description in Section 5.2. NOTE: User calibration is required to ensure the sensor is performing optimally. LED degradation over time is natural, but is corrected with this procedure. Before calibrating, be certain that the sensing window is clean (cleaning instructions, Section 6.6).
Page 148 SmartQC for fDOM Sensors (RFU or QSU) The SmartQC Score for fDOM is based on a gain factor and an offset factor. Both of these values may change as the sensor and the optics age. Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: Gain and offset are within acceptable limits.
Page 149: Sensors Overview
ISEs: Ammonium, Nitrate, & Chloride 5.16 Sensors Overview NOTE: Ammonium, nitrate, and chloride ion-selective electrodes (ISEs) should be used in freshwater applications only at depths of less than 55 feet (17 meters) and less than 25 psi. The ammonium and nitrate sensors use a silver/silver chloride wire electrode in a custom filling solution. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with ammonium or nitrate ions.
Page 150 ISEs are intended for sampling purposes and must be calibrated frequently due to sensor drift. • ISEs can be used in long-term deployments for qualitative trends. Use with an EXO wiper will deform the brush over time and may require more frequent brush replacement. The brush deformation may intensify with the fouling present in the monitored environment.
Page 151 Calibration This procedure calibrates the EXO Ammonium, Chloride, or Nitrate sensor. The sensors can be calibrated to one, two or three points. The 3-point calibration method assures maximum accuracy when the temperature of the media to be monitored cannot be anticipated;...
Page 152 Soaking EXO Ammonium Sensors are shipped in a dry container. Before initial use the sensor membrane needs to be soaked in the ammonium standard solution that is closest in value to your expected measurement range [part #003841, #003842, or #003843].
Page 153 Ammonium 3-point NOTICE: Do not expose electrodes to high-conductivity solutions. Exposure will reduce data quality and response of the sensors. During calibration of other sensors, remove the ISEs or cover them with a rubber shipping cap to avoid exposing them to conductivity standards, Zobell solution, pH buffer, or any solution with significant conductivity. In the Calibrate menu, select Ammonium, then select Calibrate.
Page 154: Sensor Drift
Remember that only trained personnel should handle hazardous chemicals Preparation Use the following procedure to prepare 10 and 1000 mg/L chloride reagents for the EXO Chloride sensor. (Nitrate and Ammonium standards can be purchased from YSI or other laboratory supply companies.) 1000 mg/L Standard Purchase solid sodium chloride from a supplier.
Page 155 Many users find it useful to swap ISEs after 30 days of deployment with freshly calibrated sensors. On the EXO platform the calibration is retained inside the sensor, so they can be calibrated in the lab and installed in the field.
Page 156 SmartQC for ISEs ISE algorithms are derived from three independent coefficients (called J, S, and A) as well as mV, temperature and salinity. J, S, and A are the calibrated coefficients and S specifically is concentration of the analyte being detected by the sensor. S is the coefficient whose gain factor is the basis of SmartQC for these sensors.
Page 157 NitraLED UV Nitrate 5.18 Sensor Overview The EXO NitraLED UV Nitrate Sensor measures nitrate as nitrogen while compensating for interferences from organic matter in freshwater environments. Refer to the NitraLED Handbook for a complete guide on sensor operation and best practices.
Page 158: Theory Of Operation
Theory of Operation UV-nitrate sensors have not supplanted traditional analytical methods such as ion-chromatography for quantitative analysis, but have become common practice as an invaluable screening method due to their inherent advantages of being chemical-free and field deployable. Traditional UV photometers use lamps such as xenon, mercury or deuterium which suffer from high power requirements and remain bulky and expensive.
Page 159 The correction is said to be loosely-adapted because this method calls for a nitrate absorbance of 220 nm, but YSI uses 235 nm, and also because this method calls for the filtration of suspended particles (turbidity) but YSI measures turbidity via YSI’s EXO Turbidity sensor and applies an internal correction since filtration is impractical for an in situ measurement for most monitoring stations.
Page 160 NitraLED Handbook more information. CAUTION: EXO NitraLED emits UV-B/C radiation within the optical cell. Personal protective equipment (PPE) for UV light, including safety glasses and gloves, should be worn when interfacing with a powered sensor. STEP 1: INSTALL CENTRAL WIPER The Central Wiper must be removed from the bulkhead to install the new spacer o-ring.
Page 161 STEP 3: INSTALL SENSOR BRACE Slide the Sensor Brace, from the NitraLED Sensor Kit [608090] or Sensor Brace Kit [608609], over the sensors. The top of the Sensor Brace should line up with the seam on the brush guard. NOTE: Make sure the Sensor Brace is seated approximately 0.5 cm below the optical sensor faces.
Page 162: Calibration Tips
NO3-N in Type I water may be used as an alternative to YSI standards. While other standards may be used, such solutions may have interfering species that could result in a calibration that is not optimal for the EXO NitraLED sensor.
Page 163 3. Pour the raw site sample into a beaker or container and use a stir bar and stir plate to keep the sediment suspended. 4. With the probe guard installed, insert the EXO sensors in the raw sample and wait for readings to stabilize. Because this raw sample may have significant debris, readings might be continuously moving;...
Page 164 SmartQC for NitraLED Sensors The SmartQC Score for NitraLED is based on a gain factor and an offset factor. Both of these values may change as the sensor and the optics age. Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: Gain and offset are within acceptable limits.
Page 165 pH and ORP 5.20 Sensor Overview Users can choose between a pH sensor or a combination pH/ORP sensor to measure these parameters. pH describes the acid and base characteristics of water. A pH of 7.0 is neutral; values below 7 are acidic; values above 7 are alkaline. ORP designates the oxidizing-reducing potential of a water sample and is useful for water which contains a high concentration of redox-active species, such as the salts of many metals and strong oxidizing (chlorine) and reducing (sulfite ion) agents.
Page 166: Signal Quality
Electrodes EXO measures pH with two electrodes combined in the same probe: one for hydrogen ions and one as a reference. The sensor is a glass bulb filled with a solution of stable pH (usually 7) and the inside of the glass surface experiences constant binding of H + ions.
Page 167 5.21 Calibration 1-point Select the 1-point option to calibrate the pH probe using one calibration standard. NOTE: While a 1-point pH calibration is possible, YSI recommends using a 2 or 3-point calibration for greater accuracy. 2-point Select the 2-point option to calibrate the pH probe using two calibration standards. In this procedure, the pH sensor is calibrated with a pH 7 buffer and a pH 10 or pH 4 buffer depending upon your environmental water.
Page 168 SmartQC for pH Sensors The SmartQC Score for pH is based on both a gain and an offset. The offset calculation is based on the millivolts recorded during sensor calibration. Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: Gain and offset are within acceptable limits.
Page 169 Additional QC Information for pH The calibration worksheet provides information that can be useful for assessing performance of the pH modules with age. Two useful parameters shown there are the “delta slope” and the “mV per decade.” In general the practice is to not use a pH module where the delta slope is less than 165 mV, and the mV per decade deviates by more than 5 units from an ideal of 59.16.
Page 170 How can one apply this information for QC? First, use the temperature compensation to determine what the slope should be for the calibration that was just performed. A calibration performed at 23°C, for instance, should have a slope of (296/298)*59.16, or 58.76. The calibration worksheet shows “mV per decade”...
Page 171 The oxidation reduction potential value shows an inverse relationship with temperature. This effect must be accounted for when calibrating the EXO ORP sensor with an ORP standard. YSI recommends using Zobell solution for calibration, but other standards may be used. Refer to the table included with your ORP standard instructions for the mV value that corresponds to the temperature...
Page 172 SmartQC for ORP Sensors The SmartQC Score for ORP is based on an offset from 0 mV. Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: Offset is within acceptable limits. Calibration was performed successfully and results are within factory specified limits.
Page 173 Rhodamine 5.23 Sensor Overview Rhodamine WT is a fluorescent dye commonly used for time of travel and tracer studies, which provide insight into the hydrological behavior of water bodies. The Rhodamine sensor is a dual-LED fluorescence sensor, featuring one LED for low concentrations and one for higher concentrations.
Page 174 μg/L. The sensor can also report in units ppb and RFU. An EXO Conductivity/Temperature sensor must be installed. The effect of temperature on the Rhodamine sensor electronics and the fluorescence of Rhodamine WT can be significant; however, the combination of these two factors is automatically taken into account by the sensor firmware providing temperature compensated readings.
Page 175 STEP 2: Prepare a 25 µg/L standard solution* of Rhodamine WT Depending on the amount (volume) of calibration solution you want to produce, use the following instructions: For 1,000 mL of 25 µg/L solution: Transfer 0.2 mL or 200 µL of the 125 mg/L Rhodamine WT base solution into a 1,000 mL volumetric flask. Fill the flask to the 1,000 mL volumetric mark with deionized or distilled water and mix well to produce a standard solution that is 25 µg/L of Rhodamine WT.
Page 176 Before proceeding with the calibration • make sure all sensors, guards, and calibration cups are clean • make sure an EXO Conductivity/Temperature sensor is installed STEP 1: Calibration Point #1 at 0 µg/L Place the sonde into a clean calibration cup containing distilled or deionized water. The software or handheld will show a graph while the sensor is stabilizing.
Page 177 SmartQC for Rhodamine Sensors The SmartQC Score for Rhodamine is based on gain factor and an offset factor. Both of these values may change as the sensor and the optics age. Guidance on interpretation of the SmartQC Score for this sensor is as follows: Green: Gain and offset are within acceptable limits.
Page 178: Total Algae
Total Algae 5.25 Sensor Overview The Total Algae (TAL) sensors are dual-channel fluorescence sensors. The “channels” are for chlorophyll and phycocyanin (TAL-PC), or chlorophyll and phycoerythrin (TAL-PE), which are measured in the water. Each sensor thus yields two data sets: for TAL-PC, one results from a blue-emitting LED that excites chlorophyll (chl) molecules, and the second results from an orange excitation beam that excites the phycocyanin (PC) accessory pigment.
Page 179 Total Algae Sensor Units The TAL sensors generate data in RFU or µg/L of pigment (chl, PC or PE) units, with RFU as the default. When using either RFU or µg/L, the sensor’s response is highly linear: a reading of 50 of either unit represents twice as much fluorescence detected as a reading of 25, for example, if the temperature is constant.
Page 180 The first option was designed for users that were accustomed to this unit in our legacy 6-Series sondes, and who want their EXO data to tightly match the cells/mL data generated by these older sondes. The algorithm applied to “match” these outputs across sonde platforms is proprietary, and it is highly advisable that when using this unit at some point users actually test the validity of the outputs for their applications.
Page 181 Use of this table requires a temperature measurement, and the best way to do this is to have an EXO conductivity/temperature sensor on the sonde bulkhead during calibration. In general fluorescence is inversely related with temperature, and this effect will be accounted for to optimize the accuracy of your calibration by using the following table.
Page 182 Step 1: Prepare Rhodamine WT Dye Solution Purchase Rhodamine WT as a 2.5% solution to follow the procedure below. Note that there are many types of Rhodamine— make sure Rhodamine WT is selected. If a 2.5% solution cannot be obtained commercially, prepare it from a solid or liquid solution to a 2.5% final concentration, or adjust the dilutions below accordingly.
Page 183 Step 3a: Calibration at zero The zero point is always calibrated first. Place the sonde, loaded with a TAL and an EXO temperature sensor, into a clean calibration cup containing clean water. It is not required that this be deionized or even distilled water; it must be free of any particles that might fluoresce and interfere with the calibration process.
Page 184 Re-zeroing the TAL Sensor Oftentimes users will perform a “cal check” in water to assess if the sensor has drifted beyond an acceptable limit defined by that user. When drift has occurred ideally a two-point calibration should be performed. However, when there isn’t an opportunity to prepare the rhodamine solutions and perform a two-point calibration, or if users are mainly interested in accuracy at the lower end of the sensor’s range, they may choose to re-zero the sensor.
Page 185 Turbidity 5.27 Sensor Overview Turbidity is the indirect measurement of the suspended solid concentration in water and is typically determined by shining a light beam into the sample solution and then measuring the light that is scattered off of the suspended particles. Turbidity is an important water quality parameter and is a fundamental tool for monitoring environmental changes due to events like weather-induced runoff or illicit discharges.
Page 186: Turbidity Standards
This method calls for this sensor type to report values in formazin nephelometric units (FNU), which is the default calibration unit for the EXO sensor. Users are able to change calibration units to nephelometric turbidity units (NTU). The EXO Turbidity sensor values in FNU and NTU units are equivalent; changing the reported unit does not alter the measured value.
Page 187 Calibration Practices The following section describes in detail how to calibrate EXO turbidity sensors. Before calibrating, be certain that the probe is very clean and free of debris. Solid particles, particularly those carried over from past deployments, will contaminate the standards and can cause either calibration errors and thereby errors in measurement.
Page 188 5.28 Calibration Tools and Practices YSI Turbidity standards that are based upon AMCO-AEPA polymer are the basis of SmartQC and EXO turbidity sensor specifications, and therefore should be used for turbidity sensor calibration. Gallon bottles are available as follows: Description Item No.
Page 189: Performing A 2-Point Calibration
Performing a 2-point calibration Pour the 0 FNU standard (or deionized or distilled water) into the clean calibration cup and immerse the probe end of the sonde into the standard. The sonde should have the sonde guard on, and if one will deploy with the copper anti-fouling guard that is likewise the guard that should be used during calibration.
Page 190 4. If a three point calibration was performed with YSI’s polymer standards, make sure the correct values from the bottles were entered during calibration. For example, make sure the EXO values, and not the 6-Series values, were entered from the label.
Page 191: Total Suspended Solids
5.29 Calculation Please follow the process below to calculate TSS. NOTE: This process cannot be performed via the EXO handheld. It must be done using Kor Software. Step 1 Make sure the turbidity probe is installed in the sonde. Step 2 In Kor Software, connect to the sonde, and navigate to Instrument and Sensors>Turbidity.
Page 192 Step 4 The message below will be displayed, asking for confirmation that the settings should be applied. Click Yes. Step 5 A message box appears which states that the coefficients have been successfully applied to the sensor. The coefficients are also displayed. Step 6 TSS values will now be displayed on the Dashboard based on the values entered via Kor and saved to the turbidity probe.
Page 193 Step 8 The units to display TSS will need to be activated separately in the EXO handheld. To add the TSS parameter to the handheld, navigate to Handheld> Display>Units>Turbidity>TSS and choose which unit to display. Click “Esc” to return to the live data dashboard. TSS will be displayed.

Sonde EXO Maintenance Watch Videos Now Storage Proper sonde storage helps to ensure proper sonde operation. To keep sondes in their best working order, users must follow these instructions. This section will identify storage as “long-term” or “short-term.” Long-term denotes storage during times of long inactivity (over winter, end of monitoring season, etc.).
Page 196: Sonde Maintenance
Sonde Maintenance Like all precision equipment, EXO sondes work most reliably when users maintain them properly. A proper inspection and cleaning can prevent several issues, including leaks. When performing general maintenance on the sonde, also check this manual’s depth and connector sections.
Page 197: Replace Exo1 Sonde Bail
Sonde Replace EXO1 Sonde Bail Sonde bails provide users with a handle for convenient transport and an attachment point for cable strain reliefs. If an EXO1 bail breaks due to impact or standard wear and tear throughout the life of the sonde, a user can easily replace it. We also recommend attaching the cable’s strain relief mechanism to the bail.

Page 199: Depth And Level Sensor Maintenance And Storage
Maintenance and Storage EXO depth and level sensors access the water through small holes (ports) located in the sonde body or bulkhead. Although users cannot access them directly, proper storage and maintenance will help to ensure reliable operation. Depth sensors can be stored dry, in water-saturated air, or submerged in clean water.
Page 200: Standard Optical Sensor Maintenance And Storage
Standard Optical Sensors Maintenance and Storage Standard optical sensors include Turbidity, Total Algae, fDOM, Rhodamine, and NitraLED sensors; these optical sensors are very low maintenance. This section identifies storage as “long-term” or “short-term.” Long-term denotes storage during times of long inactivity (over winter, end of monitoring season, etc.).
Page 201 Conductivity / Temperature Sensor Maintenance and Storage EXO Conductivity and Temperature (C/T) sensors require little maintenance or special attention for storage. As much as possible, prevent impact to the sensor’s exposed thermistor. This section will identify storage as “long-term” or “short-term.” Long-term denotes storage during times of long inactivity (over-wintering, end of monitoring season, etc.).

Dissolved Oxygen Sensor Storage EXO DO sensors require separate storage instructions from other optical sensors due to their sensing membranes. This section will identify storage as “long-term” or “short-term.” Long-term denotes storage during times of long inactivity (over winter, end of monitoring season, etc.).
Page 203: Dissolved Oxygen Sensor Maintenance And Rehydration
Maintenance and Rehydration EXO optical Dissolved Oxygen (DO) sensors require unique maintenance instructions due to their sensing membranes. Users should routinely perform these steps in order to achieve the highest levels of sensor accuracy. DO sensor caps have a typical life of 12 months.
Page 204: Dissolved Oxygen Sensor Cap Replacement
Sensor Cap Replacement Follow these instructions to replace the sensor cap on an EXO optical Dissolved Oxygen sensor once the previous cap has exhausted its usable life (typically about one year). The DO sensor cap [part #599110-01] is shipped in a humidified container, and should be stored in a 100% humid environment.

Page 207: Ph And Ph/Orp Sensor Maintenance
pH and pH/ORP Sensors 6.12 Maintenance pH and pH/ORP sensors will require occasional maintenance to clear contamination from the sensing elements. These contaminants can slow the sensor’s response time. Clean the sensors whenever deposits, biofouling, or other contamination appear on the glass, or when the sensor’s response time slows perceptibly.

Page 209: Sensor Module Replacement
6.14 Sensor Module Replacement EXO pH, pH/ORP, Ammonium, Nitrate, and Chloride sensors feature replaceable sensor modules [part #599795, 599797, 599743- 01, 599744-01, 599745-01] due to the electrolyte-depleting characteristics necessary to make such measurements. We recommend that users replace these modules as necessary—typically 12 to 18 months for pH and ORP and three to six months for ISEs, when stored properly.
Page 210 4 Inspect and service new sensor module’s o-rings Ensure that the two o-rings are not nicked or torn and have no contaminants or particles on them. If the user detects damage, carefully replace them with the extras included in the sensor module kit. Then apply a thin coat of silicone grease to each o-ring, taking care not to get any grease on the gold connector pins.

Page 212 In order to minimize the chance of water infiltration, YSI recommends annual replacement of the wiper shaft o-rings inside the EXO Central Wiper. This replacement must be performed by a YSI Authorized Service Center. EXO Authorized Service Centers are located in the United States and around the world. Please refer to the YSI website (YSI.com/Repair) for your nearest Authorized Service Center.
Page 213: Exo Field Cable Maintenance And Storage
Maintenance and Storage EXO field cables are rugged and provide years of reliable service when properly maintained. As with all field cables, they are most vulnerable at their connectors. Take extra caution to protect the connectors from debris and physical harm.
Page 214 6.17 Maintenance and Storage EXO sondes utilize wet-mate connectors that greatly reduce problems associated with traditional underwater connectors. However these connectors must be properly maintained to reap the full benefit of this design. Following these instructions will minimize most potential issues.
Page 215: Anti-Fouling Equipment Maintenance
6.18 Maintenance Many components on EXO sondes are made of an anti-fouling copper-alloy material that discourages the growth of aquatic organisms. However, longer deployment intervals and highly productive waters can result in biofouling of any equipment, so periodic cleaning may be required.
Page 216: Flow Cell Maintenance
There are two versions of the EXO flow cell: EXO1 flow cell [part #599080] and EXO2 / EXO3 flow cell [599201]; also compatible with EXO-S sondes. Flow rate of the flow cell is typically between 100 mL and 1 L per minute. Maximum flow rate depends on tubing type, size, and length.
Page 217: Storage Cases Packing Options
Carrying Case provides a secure manner in which to store your EXO equipment for travel or until the next trip into the field. As seen below, the EXO Hard-Case provides the perfect safe storage solution, though we do offer several case options.
Page 218 Ultimately, while the EXO equipment is built to withstand harsh field environments, we recommend users take care to safely store their systems while not in use. Both the EXO Hard-Sided Carrying Case and the cloth YSI case are viable options, but other non-YSI products may better suit more specialized user needs.

NOTE: Observe the pH mV readings during calibration to understand the condition and response of the pH sensor. In buffer 7, pH mVs should be between -50 and +50. In buffer 4, the mVs should be a +165 to 185 away from the pH 7 mV value.
Page 243: Orp Calibration
pH calibration 2- or 3-point NOTE: If performing a 2- or 3-point calibration, one point should be in buffer 7; however, the calibration points can be in any order. Perform steps 1-7 of the pH calibration 1-point procedure (1-Point pH Calibration).
Page 244: Depth Calibration
Altitude/Latitude: To compensate for atmospheric pressure based on elevation and gravitational pull, enter the local altitude in meters relative to sea level and latitude in degrees where the EXO handheld is sampling. Altitude effect: Varying altitudes cause approximately 90 mm change from sea level to 8000 m.
Page 245 Turbidity calibration 1-, 2- or 3-point NOTE: The sensor guard must be installed for the turbidity sensor calibration. NOTE: When performing a turbidity calibration, the first point must be zero. Select Calibration Value and enter 0.00. Perform the Calibration setup. Rinse the sensor 2-3 times with a small amount of 0 FNU (NTU) standard.
Page 246 ISEs: Ammonium, Nitrate, & Chloride Before performing the calibration, review Calibration setup. The ISEs can be calibrated to one, two or three points. A 2-point calibration without chilling a third calibration solution is extremely accurate and is the preferred method. However, if there is a large temperature variation during sampling, a chilled third calibration point is recommended.
Page 247 ISE calibration 3-point Perform the Calibration setup. Rinse the sensor 2-3 times with a small amount of standard #1.
