    Check temperature, relative humidity, atmospheric pressure, and time with a single barometer.
    Remote-Reading Barometer—Remote-reading barometers wirelessly monitor outdoor temperatures and relative humidity as well as indoor conditions. They'll transmit readings from up to 200 feet away.
    525,600 Readings—Direct-reading barometers that hold 525,600 readings store about two years’ worth of data. They’re often used in laboratories because they continuously monitor conditions, so you can track changes over time. Use their USB-A connection to transfer stored data to your PC with a USB cord (not included).

    Wireless Weather Stations

    Image of Product. Front orientation. Weather Stations. Wireless Weather Stations .
    Monitor nine different weather conditions up to 1,000 feet away. The outdoor weather sensor measures outdoor temperature, humidity, wind speed and direction, rainfall rate, total rainfall, barometric pressure, heat index, wind chill, and dew point. It wirelessly transmits readings to the console by radio signal. Console has built-in sensors to measure indoor temperature and humidity. Console can be placed on a desk or mounted to a wall.
    Cannot Be Sold To—They cannot be sold to the listed areas due to product registration requirements.
