The CHT-DS series duct-type temperature and humidity transmitter utilizes imported digital temperature and humidity sensors. It features precise pre-calibration with data stored in internal memory. The transmitter offers digital output for both relative humidity and temperature, ensuring interchangeability without complex calibration. It excels in measurement accuracy, linearity, repeatability, interchangeability, and consistency, making it suitable for environmental equipment, instrument integration, and general environmental testing.
Widely used in building automation, telecom equipment rooms, papermaking, warehousing and logistics, shopping malls, hotels, cinemas, train stations, museums, theaters, agricultural greenhouses, hospitals, meteorology, clean workshops, and other fields requiring air temperature and humidity measurement.
