Foxboro PH12 Series precision electrochemical sensors provide unique electrode technology in the 12-mm form factor. They have a durable PEEK body for strength and chemical resistance; high-temperature capability to 125 °C; greatly expanded range of applications for flat glass; non-metallic wetted parts for immunity from most process fluids; domed glass electrodes for very wide range (-25 °C to +125 °C) and very high temperature (140 °C). They are biocompatible and 3-A sanitary-compliant.
