CDT series air quality transmitters are designed for building automation systems in the HVAC/R industry. The CDT series is able to measure carbon dioxide (CO2) and temperature (T) at the same time. The industry standard NDIR measurement principle is used for measuring carbon dioxide. If you want to measure the relative humidity (rH), you can the option to this device and will measure all three parameters at the same time. Having a large touchscreen display, provides an easy and accurate configuration for the user.
The CDT2000 series transmitters calibrate themselves automatically using ABC logicTM. The ABC logicTM (Automatic Background Calibration algorithm) requires that the space in which the transmitter is used needs to be unoccupied for four hours per day so that the indoor CO2 concentration drops to the outside level. CDT2000-DC is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDT2000-DC has a premium advantage for buildings that are continuously occupied.
