Previous Page


The CDE is non-dispersive infrared (NDIR) analyzer designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Their measurement range of 0-2000ppm makes them compliant with ASHRAE and othe standards for ventilation control .

The CDE Series provides a user-selectable 4-20mA or 0-10VDC output for versatility. Microprocessor-based digital electronics and a unique self-calibration algorithm improves long-term stability and accuracy.

Microprocessor design increases accuracy and reduces installation time:

  • Non-dispersive infrared technology repeatable to 20 ppm 1% of measured value
  • Innovative self-calibration algorithm...easy to maintain
  • 5-year calibration interval (recommended)
  • Low ambient sensitivity
  • Alarm relay with set point for direct ventilation control
  • Output 4-20mA/0-10V for flexible control system interface
  • 3-year factory warranty from date of purchase
