Temperature and RH Wireless Transmitter - RHT-Air

The RHT-Air is a wireless transmitter that when coupled with the AirGate-Modbus provides an
Excellent solution for wireless monitoring of temperature and relative humidity variables. Together, they combine the ease of configuration and data acquisition operation of the RHT-RS485-LCD, which connects directly to a Modbus RTU bus, with the versatility of the wire-free installation of LogBox-RHT.

Through the IEEE 802.15.4 wireless interface, multiple RHT-Airs may talk to one or more AirGates, providing this way USB and RS485 communication paths to the main application.

The RHT-Air uses high accurate sensors for measurements of the temperature, relative humidity and dew point. It also provides a LCD display for local viewing of the measurements while allowing reconfiguration of the transmitter parameters without having to run the configuration software on the computer. The autonomy of the RHT-Air internal battery provides stand-alone operation, forgetting about any wires for either powering or communication. For applications that don't require battery operation, a version for external DC power supply can be ordered. The RHT-Air is offered for wall as well as for duct mount.
