Description
PH sensors Foxboro are available in a large number of form factors, electronic configurations (including Smart) and maintenance styles (disposable and rebuildable). Whether the application requires a 12 mm style probe or an NPT threaded version, Foxboro has the sensors to meet the requirements. Many Foxboro pH sensors use a double junction reference electrode design incorporating an ion barrier called Nafion. The Nafion keeps the silver trapped in the inner cavity so that clogging cannot occur at the outer process junction. PH sensing membranes are available in flat, rugged pH, domed pH for high temperature service, and antimony. Mounting accessories are designed for ease of use and flexibility, and range from simple bushings and flow chambers to insertion/retraction assemblies to permit the sensors to be serviced without shutting down the process line.
