PH Meter Calibration

The calibration powder with 250ml of distilled water or pure water (not included) ... Use tap water and mineral water) to open. Immerse the pH electrode in a standard mixed phosphate buffer solution at pH 6.86 and stir gently.

Press the CAL button: an automatic calibration will be performed until the displayed value and the standard pH 6.9 buffer solution are compatible with room temperature.

As above, the electrode was placed in a standard buffer solution of phosphorous acid and potassium bicarbonate at pH 4.01.

Approximately 2 minutes. The displayed value should be within error tolerance of the pH value of the buffer solution.
