Wall Mount Carbon Dioxide/Temperature Transmitter
Description
The Series CDW Wall Mount Carbon Dioxide and Temperature Transmitter combines accurate C02 measurements with a passive temperature output. The Non-Dispersive Infrared (DNIR) sensor continuously updates the calibration through a proprietary logic feature, which limits the amount of error due to drift. The CDW series is ideal for building automation systems to help control the fresh air intake in a room.
