Dwyer CDD Duct Mount Carbon Dioxide Transmitter Installation and Operating Instructions

Below you will find brief information for Carbon Dioxide Transmitter CDD Duct Mount. The Model CDD Duct Mount Carbon Dioxide Transmitter monitors the occupancy in a room by detecting the concentration of carbon dioxide in the return air duct. The non-dispersive infrared sensing technology automatically updates the calibration of the transmitter using a proprietary logic feature which limits the amount of error due to drift. The Model CDD can measure up to 2000 PPM in duct air flows less than 1500 FPM.
