Details for CDE

CO2 | Duct | Economy | No LCD


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


  • Controlling ventilation in response to occupancy
  • Facilitating compliance with ASHRAE 62.1 standard for air quality
  • Office buildings, conference rooms, schools, retail stores, etc.
