SE 655 Toroidal Conductivity Sensor


The SE 655 is a corrosion-resistant toroidal conductivity sensor for measuring pure water up to maximum conductivities of 2000 mS/cm. It features a smooth, easy-to-clean design. The SE 655 is highly accurate due to electrodeless measurement. It has a low risk of contamination because of a large sensor opening. It is suitable for hazardous locations.



  • Robust design
  • Extremely large measuring range due to inductive measuring principle
  • Insensitive to contamination
  • No process-wetted electrodes
  • High chemical resistance (PEEK)
  • Measurement in hazardous locations
  • Steam-sterilizable
  • CIP-capable
