PH And ORP Sensors

The PH And ORP Sensors is a successful development in pH sensor technology, available from Yokogawa. This sensor has the measuring technology from differential sensor and the ruggedness of the appreciated wide body FU20 design in one product. Most pH sensors are using silver/silver chloride reference cells with an open junction to the process. With the differential technology, the junction is not in direct contact with the process. This is for many applications beneficial because you will not poison silver/silver chloride reference. In a wide range of applications this solution has proven very effective and remains a cost effective solution. Lifetime of the conventional sensors dependent of regular maintenance of the pH probes. Regular, cleaning is required to eliminate reference poisoning. 70-80% of industrial users will fully benefit from using differential sensor technology in their high temperature and pressure applications. Example applications: pH monitoring in brine solutions applied in chemical industryThe bleaching process in pulp and paper SO2 scrubber applications Tail gas, Quench Tower with sulfides
