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