SE655 Toroidal Conductivity Sensor | Fixed cable | PEEK | High chemical resistance

Description

SE655 Toroidal Conductivity Sensor | Fixed cable | PEEK | High chemical resistance

Universal and precise sensor with high chemical resistance over a very large measuring range, for heavily polluted media.

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

Corrosion-resistant toroidal sensor for measuring pure water up to maximum conductivities. Smooth, easy-to-clean design. High accuracy due to electrodeless measurement. Low risk of contamination because of large sensor opening. Also for hazardous locations (SE655X).

Applications
Concentration measurement of acid and alkaline solutions, heavily polluted media, coating-forming and oil-containing media, salt spring, heavily polluted wastewaters, cooling water blowdown, concentrate monitoring, regeneration of ion exchangers
