Measuring the relative ORP
To measure the difference of the ORPs of two solutions it is best to use
two ORP electrodes. Define one of the ORP electrodes as the refer-
ence in the menu. The difference of the two voltages is displayed.
Note
The relative ORP can be determined with pH and ORP electrodes.
1
Perform the preparatory activities (see page 69).
2
Prepare the reference solution for the determination of the ref-
erence point.
3
Immerse one electrode in the reference solution.
Immerse one electrode in the test sample.
4
Highlight the channel of the electrode that is in the test sample
in the measured value display.
5
If necessary, select the U display with
<MODE>
.
6
Display the difference voltage with
