Test and maintenance equipment ORP 德国WTW

Contrary to pH electrodes, ORP electrodes do no require any adjustment, bu 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 l surfaces of the platinum electrodes can be conditioned or cleaned with the SORT/-RH.
