Electrode preparation
To measure the ORP (oxidation-reduction potential) of a solution, use a
platinum electrode especially designed for that purpose.
mV measurement with the pH electrode shows the potential of the electrode.
This measurement is useful for checking samples and the performance of the
electrode.
Refer to the electrode instruction manual and make sure you have the
correct electrode.
