pH Calibration & Measurement
1. Rinse the pH electrode
with clean water and
blot using lint-free
tissue to remove
excess water.
2. Immerse the pH electrode in pH buffer.
Perform 2-point calibration using
pH 7 and 4 for acidic sample or pH
7 and 10 for alkaline sample.
Perform 3-point calibration using
pH 7, 4, and 10 if you are unsure
of the expected sample value. It
is recommended to calibrate with
pH 7 first.
3. Press CAL button on the meter to switch
to calibration mode.
The screen will display the set pH buffer group briefly and
the will start blinking until the reading stabilizes.
