Aneroid barometer An aneroid barometer is an instrument used for measuring air pressure via a method that does not involve liquid . Although Gottfried Wilhelm Leibniz first proposed the concept of an aneroid barometer around 1700, it was not until 1844 that French scientist Lucien Vidi successfully invented it. [ 1 ]
The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...

Jack's diaries, as well as a number of his artefacts from the expedition, including his 1829 Aneroid barometer and a set of two thermometers, were bequeathed to the Museum Victoria. [ 3 ] [ 4 ] After the expedition, Jack worked during the war in an explosives factory (known as the Cordite Factory), utilising his expertise in chemistry ...
Weather stations typically have these following instruments: . Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity
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 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.
