With a large backlit display and a distinctive design, the RHT Climate is a humidity and temperature transmitter that provides high measurement accuracy and stability over a wide operating range, and calculates seven psychrometric properties in real time, making all variables available via analog current or voltage retransmission or RS485 Modbus RTU communication.
Versatile, the device allows parameter configuration, temperature and humidity simulation and forcing of the retransmission outputs — useful features for field commissioning — all quickly and easily via USB with the NXperience software or directly from the keypad. The RHT Climate also has two digital alarm outputs and an internal buzzer for audible alarms.
