The high temperature insertion type electrode is designed for periodic exposure to steam sterilization or continuous high temperature. This pH electrode is housed in a durable thermoplastic (PAS) body and is rated for temperatures up to 135°C. The use of the double Porous PTFE liquid junctions with matched viscosity electrolytes provides a reference cell which permits extended periods of pH measurements in the presence of sulfides or other silver complexing agents. This electrode also incorporates pressure compensating devices to protect the electrode from extreme temperature induced pressure deviations. Ten foot cable length and BNC connector are standard.

Application
• High Temperature Environment
• Continuous Processing Applications
• Harsh Conditions
