RHT-WM Relative Humidity and Temperature (Wall Mount)
RHT-DM Relative Humidity and Temperature (Duct Mount)
The Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM are microprocesser based instruments that incorporate high accurate and stable sensors whose information is converted to linear 4-20 mA.
Using the digital communication interface, the transmitter parameters can be configured to tailor a particular application.
The RHT-WM model is intended for wall mounting. The RHT-DM comes with a probe tip for duct mounting.

RHT-WM Relative Humidity and Temperature Modbus (Wall Mount)
RHT-DM Relative Humidity and Temperature Modbus (Duct Mount)
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 microprocesser 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.
