Page 6: Introduction
Aquameter™ Series Instruction Manual 10401-00188 Rev M 1. Introduction This manual covers the setup, operation, calibration and maintenance of the full Aquameter series of Meters, Aquaprobes and the associated AquaLink PC software. Depending upon the model of Meter and Probe you are using, some of the functions described may not be available. -
Page 7: The Aquaprobe And The Environment
Aquameter™ Series Instruction Manual 10401-00188 Rev M 2.2. The Aquaprobe and the Environment The Aquaprobe is designed to be fully submerged in water and is rated to IP68, that is to say, it is rated for continual immersion to a depth of 10 meters. 2.3. -
Page 8: Battery Installation And Care
Aquameter™ Series Instruction Manual 10401-00188 Rev M 3. Battery Installation and Care The Aquameter requires five AA size batteries. To install the batteries, loosen the two screws on the centreline of the rear of the meter and remove the battery compartment lid. Following the battery polarity markings inside the battery compartment, insert five AA cells then replace the compartment lid and tighten the screws. -
Page 9: Overview Of The Operating System
Aquameter™ Series Instruction Manual 10401-00188 Rev M 4. Overview of the Operating System The operating software in the Aquameter has been designed for simple, intuitive use. Similarly, a great deal of development work has been put into simplifying and automating the calibration procedures in the Aquameter in order to allow normal field operatives (as opposed to trained lab technicians) to achieve quick and accurate results. -
Page 10: Connecting An Aquaprobe
Aquameter™ Series Instruction Manual 10401-00188 Rev M 5. Connecting an Aquaprobe The Aquameter is designed to operate in conjunction with any one of eight different Aquaprobes (each variant is considered in later sections). To connect an Aquaprobe, align the key slot of the Aquaprobe plug with the Aquameter socket, then press the plug into the socket and tighten the retaining collar. -

Page 24: After Use
Aquameter™ Series Instruction Manual 10401-00188 Rev M 11. After Use The Sleeve on the Aquaprobe is made in two parts, which separate by unscrewing to allow cleaning of the individual electrodes. After every use, remove the protective Sleeve End Cap (if fitted) then unscrew the lower half of the sleeve as shown. -
Page 25: General Probe Maintenance
Aquameter™ Series Instruction Manual 10401-00188 Rev M 12. General Probe Maintenance Each Aquaprobe is constructed with a two-part protective aluminium sleeve surrounding the more delicate sensing electrodes. To gain full access to the individual electrodes for periodic maintenance and thorough cleaning, first unscrew the lower half of the sleeve. Next, remove the four small black countersunk screws from around the top of the upper sleeve, then gently slide the upper sleeve off the Probe body being careful not to damage the individual electrodes. -

Aquameter™ Series Instruction Manual 10401-00188 Rev M 13. pH/ORP Electrode Calibration and Maintenance 13.1. Recognising the pH/ORP Electrode The pH, ORP and combined pH/ORP electrodes are easy to recognise because they are the only electrodes that are not black. These electrodes have a clear, gel filled body. 13.2. -
Page 27: Calibrating Ph
Aquameter™ Series Instruction Manual 10401-00188 Rev M 13.4. Calibrating pH pH electrodes should be calibrated fully at least once a week to ensure optimum accuracy. Full calibration involves calibrating at pH 7.00 first, then at pH 4.01. Although the Aquaprobe allows only two point pH calibration, the pH electrodes are extremely linear and once calibrated, will read accurately over the full range of 0 –... -

Page 29: Calibrating Orp
Aquameter™ Series Instruction Manual 10401-00188 Rev M Never place the entire Aquaprobe in methyl alcohol, as this will cause irreparable damage to the DO/EC electrode. Damaged caused in this way is not covered by the warranty. If the methyl alcohol rinse does not restore the electrode, perform the following actions: Remove the electrode from the body again. - Page 30 Aquameter™ Series Instruction Manual 10401-00188 Rev M Ensure the temperature of the solution is between 5ºC and 40ºC (41ºF - 104ºF).

Page 31: Converting Orp Readings To The Hydrogen Scale
Aquameter™ Series Instruction Manual 10401-00188 Rev M 13.8. Converting ORP Readings to the Hydrogen Scale Electrochemical measurements are ultimately referred to the so-called hydrogen scale, the convention for which is that the electrochemical potential of a hydrogen electrode in contact with hydrogen gas at one atmosphere partial pressure and a solution containing hydrogen ions at unit activity is zero at all temperatures. -
Page 32: Do/Ec Electrode Calibration And Maintenance
Aquameter™ Series Instruction Manual 10401-00188 Rev M 14. DO/EC Electrode Calibration and Maintenance 14.1. Recognising the DO/EC Electrode The DO/EC electrode is easy to recognise because it has a screw-on cap and four stainless-steel EC sensor contacts on the side (see photograph). Dissolved Oxygen (DO) is measured at the end of the electrode by the components behind the removable cap. -
Page 33: Calibrating The Do Zero Point
Aquameter™ Series Instruction Manual 10401-00188 Rev M If you are going to calibrate both the Zero and 100% points at the same time, ALWAYS calibrate the Zero point first, then the 100% point. To calibrate the DO/EC electrode follow these steps: 14.5. -

Aquameter™ Series Instruction Manual 10401-00188 Rev M 2. Unscrew the DO Membrane cap from the end of the DO/EC electrode by rotating it anti-clockwise. 3. Gently brush away any scaly grey deposits from the coiled wire section of the electrode with a soft toothbrush, taking care not to damage the coil in the process. After removing the deposits, rinse the electrode with DO Electrode Filling Solution. - Page 36 Aquameter™ Series Instruction Manual 10401-00188 Rev M 14.9. Calibrating EC EC calibration is always carried out at a single point. There is a choice of three single points. These are: 1413µS/cm, 2570µS/cm (using Aquaread RapidCal solution) and 12,880µS/cm. These values have been chosen to allow accurate readings to be taken in a variety of water types.

Page 39: Turbidity Electrodes Calibration And Maintenance
Aquameter™ Series Instruction Manual 10401-00188 Rev M 15. Turbidity Electrodes Calibration and Maintenance Turbidity is measured by the Aquaprobe using a dual electrode, optical, Nephelometric technique in accordance with ISO 7027, which uses Formazin as a reference standard. The Aquameter displays turbidity in Nephelometric Turbidity Units (NTU) which are nominally equivalent to Formazin Turbidity Units (FTU). -
Page 40: Calibrating The Turbidity Electrodes
Aquameter™ Series Instruction Manual 10401-00188 Rev M The lens system in the Turbidity Electrodes is designed to focus correctly in water. When the Probe is not submerged, the system will be out of focus and random readings will occur. This is normal. The Probe sleeve forms an integral part of the turbidity measurement system. -

Aquameter™ Series Instruction Manual 10401-00188 Rev M 22. Appendix 1. The Tech Behind Aquaread’s Optical DO Measurement System 22.1. Principle of Operation The Aquaread™ AquaPlus™ Optical DO measurement system works on the principle of Dynamic Luminescence Quenching. A gas-permeable chemical known as a luminophore is excited with short bursts of blue light, which causes molecules in the luminophore to emit red photons. -
Page 61: Sensor Cap Life
Aquameter™ Series Instruction Manual 10401-00188 Rev M 22.2. Sensor Cap Life All optical dissolved oxygen sensors work on the same principle, and all must have the sensor cap containing the luminophore replaced periodically due to a phenomenon known as photo bleaching. When a sensor cap is new, the luminophore will return a large number of red photons when excited. -

Introduction The Aquaread Flow Through Cell (Flowcell) is designed for use with any model of Aquaread Aquaprobe and most third party pumping device. The Flowcell allows sample water to flow up through the Aquaprobe, passing over all the individual electrodes simultaneously. -
Page 63: Operation
Aquameter™ Series Instruction Manual 10401-00188 Rev M 23.5. Operation Connect the Flowcell to a pumping device so that sample water enters at the bottom and exits at the top. Adjust the flow rate so that there is no visible turbulence or cavitation within the Flowcell. -
