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 ...
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 the bottom centre is the aneroid (large circular silver object). As the pressure increases, the aneroid is pushed down causing the arm to move up and leave a trace on the paper. As the pressure decreases, the spring lifts the aneroid and the arm moves down. After three days the drum to which the graph is attached is removed.
He was recognised for his temperature-compensated aneroid barometer. [11] Browning's scientific instruments were used in physics, chemistry, and biology. The products he designed and manufactured included spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmoscopes, and electrical equipment such as electric lamps.

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.

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 .
