Measuring the ORP voltage

The measuring system can measure the voltage of a
solution in conjunction with a ORP electrode, e.g. SenTix
ORP.
1 Call up the Display mode with
2 Call up the measured variable U with
3 Submerse the ORP electrode in the sample.
4 Wait for a stable measured value.
Note
Note that, when measuring voltages, it can take a long time
(even several hours) until the measured value becomes
stable.
ORP electrodes are not calibrated. However, you can check
ORP electrodes using a test solution.
