The CHT-DS series duct temperature and humidity transmitter utilizes imported digital temperature and humidity sensors, pre-calibrated during production with calibration data stored internally. Featuring digital output for both relative humidity and temperature, these transmitters offer excellent interchangeability without complex calibration. They excel in measurement accuracy, linearity, repeatability, interchangeability, and consistency, making them 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.
