The EasyFerm Plus sensors are designed to withstand demanding applications in pharmaceutical and chemical industries. The pH/RX sensors enable customers to measure pH or ORP (RX) or, depending on the controller, both in parallel. It is supplied with a pre-pressurized electrolyte which prevents the diffusion of sample into the sensor. The Everef-F reference cartridge ensures that the PhermLyte reference electrolyte remains free of silver and precipitation. It withstands steam sterilization, autoclavation and CIP cleanings.

  • Ceramic diaphragm is an improved barrier of the electrode
  • Highly reliable measurements after steam sterilization, autoclavation and CIP cleanings
  • Drift-free measurement
  • Pre-pressurized reference electrolyte ensures a clog-free diaphragm
