step
1. Connect the electrodes and remove the protective cover.
2. Clean the electrode of the pH meter with distilled water first, and absorb the water attached to the electrode with filter paper.
3. Touch the "ON/OFF" button to turn on the power.
4. Insert the pH meter electrode into the liquid to be measured until the electrode is immersed in the liquid about 4cm deep, do not put the solution into the electrode connection.
5. Gently stir the solution until the value stabilizes, and then read the stable display number.
6. Touch the "HOLD" key to hold the current measurement value. If you need to re-measure, press the "HOLD" key once to release the hold state.
7. After use, press the "ON/OFF" button to turn off the power, clean the electrode with distilled water, and cover the protective cover.
PH calibration
1. Immerse the pH electrode in a mixed phosphate standard buffer solution with a pH of 6.86 (25°C) and shake it gently.
2. Use a small screwdriver to adjust the calibration potentiometer until the displayed value matches the pH value of the standard buffer solution at the solution temperature. Then wash the electrode of the pH meter with distilled water, and use filter paper to absorb the water attached to and around the electrode.
3. Insert the electrode into the pH 4.01 potassium hydrogen phosphate or pH 9.18 borax standard buffer solution.
4. When the displayed value is stable, the displayed value should be within the error tolerance range compared with the pH value of the buffer solution.
