Dpstar Group is leading supplier of HK Instruments Carbon Dioxide Transmitter,CDT series. 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. The CDT2000 series transmitters calibrate themselves automatically using ABCTM logic. The ABCTM logic requires that the space in which the transmitter is used needs to 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 is also suitable for buildings that are continuously occupied. CDT series devices include: • Separate field configurable output for each measurement parameter (CO2, rH, T) • Proportional output options including: voltage (0–10 V, 2–10 V) and current (4–20 mA) CDT2000 series device options offer: • 2” x 3” touchscreen display • Field configurable relay for any of the three parameters • Modbus configuration We are HVAC supplier in Malaysia.
