The RHT-WM-485-LCD transmitters include high precision and stability sensors for measuring relative humidity and temperature. They are microprocessor-based devices and, therefore, allow being entirely configured through an RS485 interface using the Modbus RTU command. The DigiConfig software allows the configuration of all transmitter features as well as its diagnostic procedure. The RHT-WM-485-LCD model is intended for wall mounting. The transmitter can be configured for displaying the values of measured temperature and Relative Humidity, or the values of measured Temperature and Dew Point, or the values of measured Relative Humidity and Dew Point, or the value of measured Temperature only. The communication parameters can be easily field-configured. The values for communication address, baud rate and parity can be changed using the frontal button without the need for using the configuration software.
