Measuring principle
Redox measurement
The redox potential is a unit of measurement for the state of equilibria between oxidising and reducing
components of a medium. Redox potential is measured similarly to the pH value. A platinum or gold electrode
is used instead of pH-sensitive membrane glass. Analog to the pH measurement, an integrated Ag/AgCl
reference system is used as a reference electrode.
Measuring system
A complete measuring system comprises:
- CPS42 or CPS42D ORP electrode
- Transmitter, e.g. Liquisys M CPM223/253 (with Memosens technology for CPS42D)
- Special measuring cable, e.g. CPK9 or CYK Memosens data cable for CPS42D
- Immersion, flow or retractable assembly, e.g. Unifit H CPA441
