Temperature and Humidity Transmitter for high humidity environment

AHT503-H

AHT-503H series Temperature and relative humidity(RH) Transmitter is perfect for high humidity environment. In high relative humidity (over 90% RH), the environmental temperature will be closed to the saturation. The vapor pressure gradient is not enough for effective evaporation of liquid. Thus, the sensor might stay wet and became malfunctioned. The AHT-503H transmitter equipped with special sintered sensing probe to protect the sensing elements and to avoid the measurement outage which might happen in the high humidity environment.AHT-503H adopted CMOSens technology sensors to ensure its stability and reliability of measurement, meanwhile, it equipped with 3 switchable temperature measurement range 0~50℃, -50~50℃ or 0~100℃ to enable users to deploy the transmitter in different environment. To timely monitor the temperature and RH variation, the temperature and humidity meter provide current signal DC 4~20mA, voltage signal DC 0~10V/0~5V/1~5V or digital RS485 Modbus RTU signal to transfer the IAQ data immediately to the energy monitoring system or BMS system.Most of the AHT-503H transmitters are used in the smart agriculture or poultry farming to monitor the growth environment of the plant or animal, for example, poultry farm. Furthermore, they are also used in cold chain and logistic to monitor the storage environment of food or products, for example, wine cellar or warehouse.
