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.
How to Calibrate the pH Meter
1. Before calibration, prepare a beaker containing a pH 4.00 solution, a beaker with pH 6.86 solution, and a beaker pH 9.18 solution. Make sure that each solution is 250ml and at a stable temperature of 25¡ãC.
2. Prepare 3 separate beakers with distilled water.
3. Press the ON/OFF button to turn on the meter.
4. Remove the cap and immerse the electrode into the PH6.86 buffer solution. Stir gently and wait for the value to stabilize.
5. Press and hold the CAL button for 5 seconds. Hold the electrode into the solution until the LCD screen displays a value of pH 6.86.
6. Rinse the electrode with distilled water and blot dry. Repeat steps 4, 5, and 6 for the pH 4.00 and pH 9.18 solutions.
