Single-Use Conductivity Sensors

Our PendoTECH Single-Use Conductivity Sensors measure raw conductivity and temperature with no calibration required because of pre-determined cell constant.

  • 4 – 20mA outputs for both conductivity and temperature
  • A pressure rating of 75 psi
  • Temperature normalization to 25°C

Low Cost For Single-Use Applications

Our conductivity sensors are low cost, and have the option to add a panel mount kit, DIN rail kit, and benchtop stand to work in conjunction with the conductivity monitor.


Optional One-Point Calibration By User

Our single-use conductivity sensors require no calibration because of pre-determined cell constant and the temperature measurement for compensation by our monitor is within a range from 0 to 70°C.
