pH Calibration & Measurement
1. Rinse the pH electrode
with clean water and
blot using lint-free
tissue to remove
exc ess 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.
Press
4. Press ENT button to conrm the pH reading. To abort calibration, press MEAS key.
The meter will switch to measurement
mode and the electrode icon will
appear on the screen.
Press
5. Repeat step nos. 1 to 4 to perform calibration with the next pH buffer(s).
The meter allows up to 5 calibration points for USA / NIST pH buffers and up to 6 calibration
points for DIN pH buffers.
6. Rinse the pH electrode with clean water and blot using lint-free tissue to
remove excess water.
7. Immerse the pH electrode in sample.
Make sure that the glass membrane and
junction of the pH electrode are immersed
in sample.
