The process electrode for determining the ORP is suitable for almost all applications in process water analysis and water treatment - especially in the area of waste water. It is used with the pH and ORP transmitter APM-X. Due to the plastic housing (PPS) the electrode is shock-proof and very easy to operate. The screw-in thread is replaced in most cases by a separate fitting. The electrode is suited for service with all reducing media due to the platinum ring as measuring element. (For example: chromate reduction and chlorine dosing in swimming baths.)
