RHT-AIR - Wireless temperature and humidity transmitter

The RHT-Air is a wireless transmitter which, in conjunction with AirGate-Modbus, provides an excellent solution for wireless monitoring of temperature, humidity and dew point. Thanks to the IEEE 802.15.4 wireless interface, multiple RHT-Air wireless transmitters can communicate with one or more AirGate-Modbus gateways, providing USB and RS485 communication paths to the main application.

The RHT-Air uses high-precision sensors to measure temperature, relative humidity and dew point. It also provides an LCD display for local visualization of measurements, while allowing reconfiguration of transmitter parameters without having to run PC configuration software. The internal RHT-Air battery provides autonomous operation. Optional external power source available. RHT-Air is available in wall-mounted (WM) and duct-mounted (DM) versions.
