High Pressure/ High Temperature Conductivity Sensor SC42/SX42

High Pressure – High Temperature Contacting sensor primarily designed for Boiler Blowdown and Condensate Leak detection applications. These conductivity cells have extremely high temperature and pressure ratings: the threaded types can handle 16 bar at 200°C and the flanged types can handle 40 bar at 250°C.

Yes. The Cation Differential pH and ORP sensors have a glass electrode that needs a 2 point calibration performed regularly. Because of the Cation Reverence electrode you must use special buffers with a constant sodium ion concentration. This calibration is needed to compensate for the change in response of the glass electrodes. These changes are normal and are caused by aging or chemical attack, and they are accelerated at higher temperatures.
