The CWE are non-dispersive infrared (NDIR) sensors designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Their measurement range of 0 to 2000 ppm makes them compliant with ASHRAE and other standards for ventilation control. The CWE series provides a user-selectable 4 to 20 mA or 0 to 10 VDC output for versatility. Microprocessor-based digital electronics and a unique self-calibration algorithm improves long-term stability and accuracy.

  • Microprocessor based design increases accuracy and reduces installation time
  • Non-dispersive infrared technology (NDIR) repeatable to +/-20 ppm +/-1% of measured value high accuracy measurement
  • Sensitivity - low ambient sensitivity
  • 4 to 20 mA/0 to 10 VDC output for flexible control system interface
  • Self-calibrating - innovative self-calibration algorithm easy to maintain, 5 years calibration interval
  • Non-dispersive infrared, diffusion sampling sensor
