7. Platinum combination electrodes with Ag/AgCl reference system with 3 mol/l KCl electrolyte are
recommended for redox potential measurements (e. g. EMC133-K010-U).
The description of the used electrode is listed in the separate instructions for use for the sensor.

Configuration of the fixed temperature
As the pH measured value is always temperature-compensated, the temperature of the measuring and
calibration media must be measured or set up as a fixed temperature.
If the fixed temperature is activated, it is used for temperature compensation.
