Temperature, humidity, pressure regulator with two relay and RS485 outputs
BRAND
Humidity, temperature, atmospheric pressure transmitter with two relay outputs. Outdoor, indoor use.
Built-in relative humidity, temperature, pressure sensors. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Three two-state inputs.
