The Delta CO2 Duct and Rough Service Sensors are an accurate and reliable way of incorporating demand controlled ventilation. They measure the CO2in a range of 0 to 2,000 ppm with a 0 to 10 VDC output.
The Delta CO2 Duct and Rough Service Sensors are an accurate and reliable way of incorporating demand controlled ventilation. They measure the CO2in a range of 0 to 2,000 ppm with a 0 to 10 VDC output. The non-dispersive infrared (NDIR) technology has been optimized for periodically unoccupied areas and features automatic background calibration over a long time period to reduce drift. The Delta unit also has continuous automatic air pressure compensation for accurate readings despite the weather or altitude.
The Duct unit samples duct air using an aspiration tube. The Rough Service unit features a ventilated BAPI-Box and is ideal for areas such as outdoor air plenums, equipment
rooms, attics, green houses and warehouses. Optional indication of the CO2level as “Good, Fair or Poor” is available as a three-color LED on the front of the unit.
