Calibration Tips:
1. Dissolve pH buffer powder in 250ml of distilled water.
2. Turn on the PH meter and clean the electrode in distilled water, then immerse the electrode in the pH standard solution.
3. Press the’ CAL’ button, wait until the reading is the same as the PH value of buffer powder and steady.
4. Clean the electrode with distilled water and dry it.
How to measure PH value:
1. Remove the protective cap from the handheld pH meter. Rinse the electrode with distilled water and let it dry.
2. Press the ON/OFF button to turn on the unit. Dip the electrode in the target solution, making sure the whole electrode is submerged.
3. Stir the solution gently and wait for the value to stabilize. The LCD screen will display both the temperature and pH.
