XEROLYT®PLUS pH probe for easy handling and direct mounting

InPro 4501VP is a rugged pH probe with PVDF shaft, built-in temperature sensor and Solution Ground with diagnostics for chemical applications and high flow-through rates. Also available with fixed cable.

Features and Benefits

Low maintenance
A solid XEROLYT®PLUS polymer electrolyte (no refilling and pressurizing) in direct contact with the process media via an open junction. No clogging in contaminated media due to the open junction.
Reliable measurements in heavily contaminated liquid media
It is suitable in industrial processes or in wastewater applications with highly contaminated solutions, emulsions and suspensions, sulfide-bearing media, suitable also for high flow-through rates. The solution ground assures accurate measurements with a built-in sensor diagnostics tool.
Rugged PVDF body design
Dual 1" NPT threads allow the sensor to be screwed directly into immersion tubes, pipes, process vessels etc, due to the polymer body design, protecting the electrode from mechanical damage, acting as a housing at the same time.
Flat membrane for abrasive media
  • The electrode has a flat glass membrane with protective stand-offs, for media with high content of fibers, particles etc.
