Buffer used
Dispose of the used buffer solution.
For more information: refer to the
buffer solution safety data sheet.
Valid calibration values
Valid calibration:
– Zero point -60mV…+60 mV
– Slope 55 mV/pH…62 mV/pH
You need two test containers with buffer
solution for calibration. The pH values of
the buffer solutions should be at least 2
pH values apart. Thoroughly rinse the
sensor with water when changing the
buffer solution.

Then press
2. Rinse the sensor thoroughly with
water before drying with a cloth
(pad dry, don't rub)
3. Immerse the sensor in test con‐
tainer 1 containing buffer solution
(e.g. pH 7). When doing so, move
the sensor gently
