CDT series Air Quality Transmitters are engineered for building automation systems in the HVAC/R industry. The CDT Series measures carbon dioxide (CO2), utilizing the industry standard NDIR measurement principle, and temperature (T). Optional relative humidity (rH) measurement is also available in the same device. CDT series devices are available with large touchscreen display making configuration of the device quick and easy.
