Description
multi-parameter water quality tester 3 in 1: pH TDS TEMP How to Calibrate the PH Meter? Take ph 6.86 standard solution calibration as an example: 1. Press the ON/OFF button to turn on the meter, and then press MODE/CAL button adjust the tester to pH mode; 2. Put the electrode into pH 6.86 standard solution, waiting for the readings to stabilize (usually 5~10 Seconds); 3. Press and hold the MODE/CAL button and release after 6 seconds; 4. Until the readings of pH 6.86 is no longer flashing, the calibration of pH 6.86 is completed; 5. Repeat the above steps if you need to calibrate pH 4.00 or pH 9.18.How to make a standard solution?Take ph 6.86 standard solution as an example: 1. Add the pH 6.86 buffer powder into beaker with 250ml of distilled water; 2. Stir until the powder has completely dissolved, then pH 6.86 standard solution is completed; 3. Repeat the above steps if you need to make other standard solutions.How to use the pH meter?1. Press the ON/OFF button to turn on the unit, and then press MODE/CAL button adjust the tester to pH mode; 2. Dip the electrode in the target solution, making sure the whole electrode is submerged; 3. Wait a few seconds for the reading to stabilize, and the LCD screen will display both temperature and PH value. 4. Dry the electrode with a cloth after use.

KEY FEATURES
- 3-in-1 water tester: PH meter has a three-in-one function, which can measure PH, TDS and temperature with high precision at the same time.
- ±0.1 pH Accuracy and 3-Point Calibration: With high sensitivity glass probe, PH meter’s full measurement range of 0-14pH, 0.01 pH resolution. And pH meter uses a 3-point calibration method, calibrating the electrode to solutions of pH 4.00, pH 6.86, and pH 9.18 to ensure the accuracy of your measurements.
- Backlit LCD Design: Don’t worry about seeing the displayed value when there is insufficient light. Wiztech PH meter features a green Backlit LCD to help you see the measurement clearly in any situation.
- Automatic Temperature Compensation: No longer need to pay attention to the temperature of testing liquid, this meter can accurately determine the pH value of the sample in the temperature range of 0 °C-60 °C (32 °F-140 °F), so it can solve the inaccurate problem caused by changing the liquid temperature.
- Wide applications: The instrument is ideal for aquarium, daily household, hydroponics, beer brewing, swimming pool, lab or any other liquids.
