4.2.3 Measuring the ORP voltage
In conjunction with an ORP electrode, e.g. SenTix ORP, the measuring
instrument can measure the ORP voltage (mV) of a solution.
Note
ORP electrodes are not calibrated. However, you can check ORP elec-
trodes using a test solution.
1 Perform the preparatory activities according to section 4.2.1.
2 Submerse the ORP electrode in the sample.
3 Press the <> <> keys until the U status display appears.
The ORP voltage (mV) of the test sample appears on the dis-
play.
4 Wait for a stable measured value.
