The RHT-WM-485-LCD and RHT-DM-485-LCD transmitters include high precision and stability sensors for measuring temperature and relative humidity. They are microprocessed devices and, therefore, allow being entirely configured through a RS485 interface, using the Modbus RTU commands. The DigiConfig allows the configuration of all transmitter features as well as its diagnostic procedure.
