The aneroid barograph is an important instrument at a meteorological station. Why?
An aneroid barometer is an instrument for measuring pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi ,it measure atmospheric pressure, often specially calibrated for use as an altimeter, consisting of a box or chamber partially exhausted of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air.
mercury barometers, even to this day, are the most accurate barometers, they are not without drawbacks. Trying to read a mercury barometer on board a ship caught in a hurricane is not easy. The idea for a mercury-free barometer (an aneroid barometer) first occurred to Gottfried Leibniz (coinventor of calculus) around 1700. 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. Aneroid barometers function by measuring the expansion and contraction of a hollow metal capsule.
So in this way of use it is an important instrument in meteorological station.
