CS40 sensors

For in-line retractable installations, the CS40 two-electrode conductivity sensor comes complete with a 1" isolation ball valve. Insert the sensor directly into processes up to 250 PSIG.

  • Hot Tap Insertion Sensor
  • Ratings from 100PSIG @ 150oC to 250PSIG @ 205oC
  • Designed for 1 inch male NPT ball valve
  • Wide range of cell constants 0.05/0.1/1.0
  • 316 SST electrodes, O-ring options EPDM (Std), Viton (Special), Buna-N (Special)


For applications where there is no sample line, the CS40 two-electrode sensor offers a simple method of removing and isolating the sensor for cleaning and calibration.
