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 ...
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 ...
The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales. The 20th century developed new remote sensing tools, such as weather radars, weather satellites and wind profilers, which provide better sampling both regionally ...

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 ...
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 ...

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.
