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.
