Barometer barometer.

The most common barometer used in homes is called an aneroid barometer. This type of barometer does not contain any liquid, instead there is a flexible metal box inside of the instrument. Most of the air is removed from the sealed metal box and an internal spring keeps the box from collapsing. As the air pressure changes, the box flexes:A mercury barometer is a device that uses the various physical properties of mercury contained in a tube to measure barometric pressure, also known as air pressure or atmospheric pressure.
