The RHT-Air is a wireless temperature and relative humidity transmitter, that can be connected to an AirGate Modbus so it's registers can be read when the unit is in operation.

Multiple RHT Airs can communicate with one or more AirGate Modbus units. The RHT-AIR can be configured entirely on the device, using the on-board LCD screen, or via USB or IEEE 802.15.4 using Modbus RTU commands. Highly accurate sensors provide precise measurements for temperature, relative humidity and dew point.

The unit comes with an antenna and power supply cable. The sensor module can be changed at any time using the replacement sensor modules.
