RHT-MOD relative humidity transmitters are designed for building automation systems in the HVAC/R industry. The RHT measures relative humidity (rH), and temperature (T).
Configuration is also possible via Modbus network. RHT devices are available with large touchscreen display making configuration of the device quick and easy.
RHT-MOD devices include:
