Duct Mount Carbon Dioxide Transmitter

Dwyer Instruments, the preferred source for complete range of practical and affordable instrumentation, is announcing the release of its new model CDD Duct Mount Carbon Dioxide Transmitter. 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 that limits the amount of error due to drift. The Model CDD can measure up to 2000 PPM in duct airflows less than 1500 FPM.
