Aneroid barometer. An aneroid barometer is an instrument used for measuring air pressure via a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, [23] 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 ...
In 1844 he invented the barograph, that is, a device to monitor pressure, a recording aneroid barometer. [1] Passionate about his work, Vidi spent all his wealth to fund his research on the barograph. The invention proved successful, and Vidi managed to make profit of it, despite several legal battles.
A barograph fitted with five aneroid capsules stacked in series, to amplify the amount of movement. Alexander Cumming, a watchmaker and mechanic, has a claim to having made the first effective recording barograph in the 1760s using an aneroid cell. [1] Cumming created a series of barometrical clocks, including one for King George III. However ...

In aircraft, an aneroid altimeter or aneroid barometer measures the atmospheric pressure from a static port outside the aircraft. Air pressure decreases with an increase of altitude—approximately 100 hectopascals per 800 meters or one inch of mercury per 1000 feet or 1 hectopascals per 30 feet near sea level .
Barograph – an aneroid barometer that records the barometric pressure over time and produces a paper or foil chart called a barogram; Barometer – an instrument used to measure atmospheric pressure using either water, air, or mercury; useful for forecasting short term changes in the weather
