Wall Mount Carbon Dioxide Transmitters

February 8, 2013

Dwyer-CDW2The 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.
