How to use the digital ph tester?

1. Remove the protective cap and protective film on the screen.

2. First rinse the electrode with distilled water and vacuum it with filter paper.

3. Turn on the meter by pressing the "ON/OFF" button.

4. Immerse the electrode of the pH meter in the solution to be tested (not above the immersion line).

5. Stir gently and wait about 30 seconds for the reading to stabilize.

6. Then clean the electrode with clean water and switch off the meter by pressing the "ON/OFF" key.

7. Always replace the protective cap after use.

Water PH tester calibration

? Turn on the pH meter.

? Dissolve each buffer solution in 250 ml of distilled water.

? Immerse the electrode in the pH 6.86 solution (at a temperature of 25℃).

? Press and release the "CAL" (calibration) key for 5 seconds.

- The display will start flashing "6.86".

- Wait until the display stops flashing.

- Rinse the electrode with distilled water and allow it to dry.

? Repeat the above steps with 4.01 pH buffer powder and 9.18 pH buffer powder.
