Aneroid barometer. An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule ...

A metal cell which contains a small amount of air or a series of these cells combined together operate the aneroid barometer. When the air pressure increases, the sides of these cells come together quickly. The base of the instrument secures one side.
May 21, 2018 · Aneroid barometers are the most common barometers in use today. They are the circular, brass, clock-like instruments with a sweep indicator pointing to the current barometric pressure. They are commonly seen in weather stations and on board boats.
A barograph is a barometer that records the barometric pressure over time in graphical form. This instrument is also used to make a continuous recording of atmospheric pressure.
