Italian scientist Evangelista Torricelli invented the barometer in the year 1643. He studied the characteristics of mercury when placed in a vacuum and used that theory to develop the first barometer.
A barometer to mercuryMESCHENMOSER ARTHUR
In 1643, Evangelista Torricelli invented the first barometer. He figured that if he had a vacuum, an airless space, he could compare the ever-present atmospheric pressure with zero. Torricelli placed a vacuum contained in a glass tube on top of a larger container of mercury. The air pressed ...
Abarometeris a device that reads atmospheric pressure. It uses liquid mercury to predict the weather by tracking atmospheric pressure changes resulting from the movement of warm and cold weather systems. If you are using an analog barometer at home or a digital barometer on your cell phone in t...

He also noticed that height of the mercury varied with changes in outside weather conditions. Figure 4: Diagram showing the construction of Torricelli's barometer. The most common type barometer used in homes is the aneroid barometer (Figure 5). Inside this instrument is a small, flexible ...
Pressure can be measured through the use of an instrument called a barometer. One of the oldest forms of a barometer is called the mercury barometer. The use of this instrument for pressure measurement is directly related to the old "mm of Hg" u...
engineering student — wanted to find the building engineer and offer to give them the barometer in exchange for the height of the building. By the same token, you could find the temperature by monitoring a standard thermometer with a camera or even a level sensor which is a topic for ...

Micromanometers are precision instruments which typically measure from very low pressures to 50 mm of mercury (6.7 kilopascals). The barometer is a sp...
