Test and Maintenance Material ORP

Contrary to pH electrodes, ORP electrodes do not require any adjustment, but merely a test in a special solution that generates a reproducible millivolt signal. The filling for the ORP electrodes is the usual 3 molar KCI solution, if not described otherwise. A special electrolyte is needed for the silver electrode. The metal surfaces of the platinum electrodes can be conditioned or cleaned with the SORT/-RH.
