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.
