Wall Mount Carbon Dioxide Transmitters

The Series CDW2 Wall Mount Carbon Dioxide Transmitters from Dwyer Instruments monitor ambient carbon dioxide conditions for variable air volume (VAV) on demand ventilation systems. Universal current/voltage temperature and humidity outputs are also available to reduce the number of instruments mounted on the wall. The Non-Dispersive Infrared (NDIR) sensor continuously updates the calibration through a proprietary logic feature, which limits the amount of error due to drift. A duct mount and a heated outside air enclosure are available enabling the CDW2 to be used in different environments.
