The standard electrode for determining ORP is suited for almost all applications in the area of process water analysis and water treatment. It is used with the pH and ORP transmitter APM-X. The dirt-repelling ring diaphragm made of PTFE allows the electrode to be used as well under difficult conditions, for example in very dirty or oily media. To extend the service life the combined electrode is filled with KCl gel and Electrode contains a long discharge plug-in head plate. It is thus very easy to Pg 13.5 operate and requires little or no maintenance. The builtin salt bridge offers improEPDM O-ring ved protection against electrode poisons such as S2Solid electrolyte (KCl-Gel) or CN-. The length of the electrode is 120 mm. The connection head is a conduit thread 13.5 screwing.
