Computer illustration of a barometer. A barometer is a device used to measure atmospheric pressure and its trend. The black needle is positioned manually. The red needle moves of its own accord, and its position relative to the fixed black needle indicates whether the atmospheric pressure has increased or decreased. This instrument is reading a low pressure of about 998 millibars.
