MeteoTemp RH+T with pressure

3-in-1 sensor probe with the same form factor as above 2-in-1 probe. Adds Pressure to the already superb Temperature, Humidity, Dew Point and Frost Point probe without increasing power consumption to maintain the same WMO accuracy requirements for Temperature and Humidity. Features a highly reliable sealed barometric pressure transducer in the sensor head.
