    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).
