How to use 

1.The temperature of the measured solution should be the same as the temperature of the standard buffer. Therefore, you must adjust the temperature regulator or slope adjustment knob before use.

2.The advanced pH meter | acidity meter is equipped with a temperature compensation system in the line.

3.After the first calibration, the instrument can automatically adjust the temperature change. When measuring, first rinse the two electrodes with distilled water, gently blot the remaining solution on the electrodes with filter paper, or wash the electrodes with the test solution.

4.Then, immerse the electrode in the beaker containing the solution to be tested, gently shake the beaker to make the solution uniform, press the reading switch, the value pointed by the pointer is the pH value of the solution to be tested, and repeat several times until the value remains When the digital pH meter | acid meter changes within less than 0.01 pH value within about 10s, it indicates that a stable reading has been reached.

5.After the measurement, turn off the power, rinse the electrode, and immerse the glass electrode in distilled water.
