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.

Overview

PendoTECH Single-Use Conductivity Sensors and Conductivity monitor integrate for highly accurate conductivity and temperature measurement without the need to calibrate the conductivity electrode because of its predetermined cell constant. For use in critical bioprocess operations, the sensor monitor reads conductivity and temperature for up to two sensors. There is temperature normalization to 25°C with an adjustable mS/ °C factor. The monitor has 4 – 20mA outputs for both conductivity and temperature and an RS232 output for data collection to a PC. With a pressure rating of 75 psi, the PendoTECH Single-Use Conductivity Sensors materials that are in contact with the product fluid path meet USP Class VI requirements, both pre and post gamma exposure.
