pH and Redox Electrodes

Monitoring of the parameters pH and redox (ORP) is most important in many different industry processes to reduce cost and optimize the yield. The requirements of many industry processes are different. In chemical processes the material has to withstand acids or caustic strong solutions under for example high temperatures. The electrodes must also be certified for use in hazardous areas.

In pharmaceutical and food processes measuring systems have to meet hygienic design, and must withstand many sterility cycles and provide traceability for validation purposes. METTLER TOLEDO offers a wide range of different product families (liquid, gel, polymer, glass-free) combined with special housings, cables and transmitters which forward the measurement values to a process control system. Our high quality products meet all the specific needs as conformity to legislations (ATEX, FM, EHEDG) or specific accuracy or ruggedness.
