RHT MODBUS Relative Humidity and Temperature Transmitters.

The RHT-WM-485-LCD and RHT-DM-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 while the RHT-DM-485-LCD model is equipped with an elongated sensor rod for installation in ducts or through walls.
