Conductivity Monitor

Our PendoTECH Conductivity monitor reads conductivity through an mS/cm temperature adjustment that normalizes conductivity readings to 25°C.

  • Reads conductivity and temperature from sensor
  • Perform temperature normalization to 25°C
  • Reads 2 sensors

Low cost for single use applications

Our Conductivity monitor requires no calibration because of pre-determined cell constant. They also feature optional one-point calibration by user and are low cost for single use applications.

Integrates With Conductivity Sensors

Our PendoTECH conductivity monitor was created to work with our sensors, and are qualified for use up to 10psi (5psi after gamma irradiation).


Featuring the ability to read temperature and conductivity, our PendoTECH Conductivity Monitor was created to work in tandem with our PendoTECH Single-Use Conductivity sensors. This sensor performs temperature normalization to 25°C with adjustable mS/ °C factor, as well as 4 – 20mA outputs for both conductivity and temperature. There are both panel mount and benchtop stand versions available.
