Measuring principle
ORP measurement
The oxidation-reduction potential is an indicator of the equilibrium between oxidizing and reducing
substances in the medium. The oxidation-reduction potential is measured with a gold or platinum
electrode instead of the pH-sensitive glass membrane. As in the case of pH measurement, an
integrated Ag/AgCl reference system is used as the reference electrode.
Measuring system
A complete measuring system comprises:
- ORP electrode CPS72 or CPS72D
- Transmitter, e.g. Liquiline CM42 or Liquiline CM44x (for CPS72D with Memosens technology)
- Special measuring cable. e.g. CPK9 or Memosens data cable CYK10 for CPS72D
- Immersion, flow or retractable assembly, e.g. Cleanfit H CPA475
