CDE | CO2 | Duct | Economy | No LCD | Veris (OBSOLETE)

See the new CD2E, which has a larger operating temperature range, a selectable co2 measurement range (0-2000/5000 PPM), and an additional output spec option of 0-5 vdc.

The CDE 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 CDE 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
