    hengko advantageHT-800 series miniature humidity transmitter adopts RHT series temperature and humidity transmitter imported from Swiss Sensirion, which can collect temperature and humidity data at the same time. It has the characteristics of high accuracy, low power consumption, and good consistency.
    The collected temperature and humidity signal data and the dew point data can be calculated at the same time, which can be output through the RS485 interface;
    Modbus-RTU communication, can be connected with PLC, man-machine screen, DCS, and various configuration software, to achieve temperature and humidity data acquisition.
