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. Also features triple lightning protection and Surge, Transient & ESD protection.
MeteoTemp RH+T has proven to have one of the lowest measurement uncertainties in the market for combined temperature and humidity measurement. A high-quality sealed barometric pressure sensor adds unbeatable value to the already exceptional MeteoTemp RH+T. Combined output features temperature, humidity, dew point, frost point & barometric pressure data.
Ultra-low power performance is not affected by the addition of pressure sensor. Total combined power consumption remains around 800 µA, with the addition of only 20 µA by the pressure sensor to maintain the 5x advantage over most meteorological temperature and humidity probes.
