5/6 & Ion 6 1. INTRODUCTION Thank you for purchasing pH 5/6 or Ion 6 meter series. These microprocessor- based handheld meters are economical and easy to use. It has a large custom LCD (Liquid Crystal Display) for clear and easy reading.
2. GETTING STARTED 2.1 Description of Keypad Functions pH 5/6 has four keys and Ion 6 meter has six keys on its splash-proof keypad with tactile feedback. The common keys include ON/OFF, HOLD/ENTER, CAL and MODE keys. Ion 6 meter has additional keys.
Instruction Manual pH 5/6 & Ion 6 2.2 Description of LCD Annunciators The meter has a large custom LCD that consists of 3½-digit segments and operation annunciators for pH, mV or C (Temperature). Note that there is no annunciator shown in Ion mode. Other annunciators include “HO” (when the HOLD function is activated) and “LO”...
Instruction Manual pH 5/6 & Ion 6 2.4 Inserting New Batteries The battery compartment is found at the back of instrument. To open the battery compartment, push in the direction of arrow and lift up the cover. Note the polarity of battery before inserting into position. After replacement, place cover back and press down until it locks tight.
Instruction Manual pH 5/6 & Ion 6 BNC of pH/ORP Phono jack of electrode or ISE Temperature probe Insert the mini phono jack of temperature sensor into the socket on the meter. Unplug the phono jack when not in use or you measure pH without any temperature compensation.
Instruction Manual pH 5/6 & Ion 6 3. CALIBRATION 3.1 pH Calibration The meter is capable of calibrating up to 3 points using USA or NIST (nSt) pH buffer standards or 2 points with Low Ionic (Pb) pH buffer standard. All new calibration values will automatically override existing data.
Instruction Manual pH 5/6 & Ion 6 3.2 Selection of pH buffer standards You must set the meter to accept either USA, NIST (nSt) or Low Ionic (Pb) pH buffer standard values before calibration. The factory default is USA standard. If you wish to abort this operation press the CAL key at any sequence and the meter reverts to pH measurement mode.
Instruction Manual pH 5/6 & Ion 6 3.2.2 pH Calibration using USA standard buffers 1. Pour a known pH buffer standard solution into a clean, dry container, e.g. pH 7.00. Power on the meter and it automatically enters into measurement mode. Select pH mode by pressing MODE key if necessary.
Instruction Manual pH 5/6 & Ion 6 3.2.3 pH Calibration using NIST standard buffers Pour a known pH buffer standard solution into a clean container, e.g. pH 6.86. Power on meter, and it automatically enters into measurement mode. Select pH mode by pressing MODE key if necessary.
Instruction Manual pH 5/6 & Ion 6 3.2.4 pH Calibration using Pb standard buffers Pour a known pH buffer standard solution into a clean container, e.g. pH 6.97. Power on meter, and it automatically enters into measurement mode. Select pH mode by pressing MODE key if necessary.
Instruction Manual pH 5/6 & Ion 6 3.3 Ion Calibration (For Ion 6 only) The Ion 6 meter is capable of up to 3-point ion calibration (minimum 2 point) with standard solutions to ensure accuracy across the entire range of the meter.
Instruction Manual pH 5/6 & Ion 6 3.3.1 Multi-point Ion Calibration 1. In case if you need to start calibration using 1.0 ppm standard solution, you can skip the 0.1 ppm calibration option (as mentioned * below). 2. For this instance let’s take 1.0 ppm calibration. To begin, pour a known 1.0 ppm standard solution into a clean container.

Instruction Manual pH 5/6 & Ion 6 9. Press ENTER key to confirm 2 point calibration (e.g. 10.0 ppm) and the display will show the next calibration option, 100.0 ppm. To exit from 2-point calibration, press CAL key and the LCD shows “PXX mV”...
Instruction Manual pH 5/6 & Ion 6 3.4 Millivolt (mV) Calibration (for pH 6 only) mV calibration is performed for ORP or Redox measurements, where you can adjust its mV value as a base value for measurements. 1. Press MODE key to enter mV mode, the LCD displays “mV”.
3. Press CAL key to enter temperature calibration mode. The LCD shows “CA” momentarily and displayed reading flashes. 4. Press keys (for Ion 6) or INC key (for pH 5/6) until the LCD display shows the desired temperature. The meter allows an adjustable maximum value of ± 5 from factory default.
C or last set temperature value. 4. Press key (for Ion 6) or INC key (for pH 5/6) until the displays shows the desired temperature. You can set any value from 0 to 100 5. To cancel or abort this operation, press CAL key. Note no new value will be stored into its meter‘s non-volatile memory.
Instruction Manual pH 5/6 & Ion 6 4. MEASUREMENT 4.1 Taking Measurements 1. Before measurement, rinse pH/ORP electrode or Ion Selective Electrode (ISE) and temperature probe (except Ion 5) thoroughly with tap or distilled water to remove any impurities stuck onto the bodies of probes.
Instruction Manual pH 5/6 & Ion 6 5. ELECTRODE CARE AND MAINTENANCE For best results, always keep the ISE capped dry and pH/ORP electrode bulb wet. Store the pH/ORP glass bulb with pH electrode storage solution. Other pH buffers are also suitable. NEVER use deionised water for storage. Wash the probes thoroughly with distilled water after each use.
Instruction Manual pH 5/6 & Ion 6 7. SPECIFICATIONS Model pH 5 pH 6 Ion 6 Ion Range 0.01 to 1999 ppm Resolution 0.01 ppm for 0.01 to 0.99 ppm; 0.1 ppm for 1.0 to 199.9 ppm; 1 ppm for 200 to 1999 ppm...
