With a wide backlit LCD and distinctive design, the RHT Climate is a relative humidity and temperature transmitter that provides highly accurate and stable measurements over a wide operating range. It calculates in real time seven psychrometric properties and all variables will be available in current or voltage retransmission or by RS485 Modbus RTU communication.

Versatile, the device allows parameters configuration, temperature and relative humidity simulation and retransmission signal generation, useful features for fast and easy in the field commissioning through USB with NXperience or directly over the keyboard. The RHT Climate also has two digital alarm outputs and an embedded buzzer for sound alarm.
