Veris Industries CDE Sensor

The Veris Industries CDE is a high-performance duct mount CO2 sensor specifically engineered for Demand Control Ventilation (DCV) in commercial HVACR environments. Built with Non-Dispersive Infrared (NDIR) technology, this 0-10V/4-20mA selectable transmitter provides precise indoor air quality monitoring across a 0 to 2000 ppm range. The high-impact ABS plastic enclosure ensures durability in rigorous duct environments, while the microprocessor-based digital electronics prevent long-term drift through a self-calibration algorithm (TEMA/ABC). This 24V AC/DC sensor is a critical component for contractors aiming to achieve ASHRAE 62.1 compliance and optimize energy efficiency by reducing outdoor air intake during low-occupancy periods. Its diffusion sampling method and velocity pressure pickup tube allow for accurate readings without the need for frequent field adjustments, making it a reliable choice for building automation systems in schools, offices, and retail spaces.

• Field-Selectable Outputs: Easily toggle between 4-20mA and 0-10Vdc via an onboard switch for seamless integration into various DDC controllers.
• Enhanced Stability: The integrated self-calibration algorithm maintains NDIR sensor accuracy (±30 ppm ±2%) and extends service intervals.
• Rugged Construction: The high-impact ABS plastic housing is designed to withstand the vibrations and pressures typical of HVAC ductwork.
• Universal Compatibility: Operates on standard 24VAC or 20-30VDC power, streamlining the installation process for field technicians.

How often does this sensor require calibration?
Standard industry practices recommend a verification check every 5 years in most commercial environments, as the electronic self-calibration logic handles baseline drift automatically.

What is the proper orientation for the duct probe?
For accurate air quality measurement, the probe should be installed so the largest surface area is perpendicular to the airflow, ensuring the diffusion sampling ports receive a representative air sample.

Can I use this in high-humidity environments?
The Veris CDE is rated for 0-95% RH non-condensing. Ensure the sensor is installed at a point in the duct mount where condensation will not form on the NDIR element.
