Digital Barometer with Wireless Temperature-RH Sensor


Digital Barometer with Wireless Temperature-RH Sensor

The #DBAR880 measures and displays indoor and outdoor temperature, relative humidity (RH) and barometric pressure. Because it also tracks 12-hour trends in pressure, it can serve as a  personal weather forecaster.
