evangelista torricelli
The first person to invent the barometer. Since it was the first one, it was also the first "longest" one (and the first "shortest" one as well).
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
The first barometer was made by the Italian physicist Torricelli in about 1640.
It is called a barometer, first developed in the 1600's
Barometer is an instrument used to measure atmospheric pressure.The first barometer was built by Francis Bacon. Later in 1644, Evangelista Torricelli, built the first instrument with mercury.
To measure the local pressure of the Earth's atmosphere, Torricelli invented the first Mercury Barometer.
In Florence, Italy in 1644, Evangelista Torricelli built the first mercury barometer, at the Florentine Academy.
The first barometer is thought to have been built unintentionally by Gasparo Berti, sometime between 1640 and 1643.[1] Evangelista Torricelli, is generally credited with inventing the barometer. Got the info from wiki.
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
Air pressure is measured with a barometer.
