WebBarometric pressure can be measured using a barometer, a device invented in 1643 by one of Galileo’s students, Evangelista Torricelli (1608–1647). A barometer may be constructed from a long glass tube that is closed at one end. It is filled with mercury and placed upside down in a dish of mercury without allowing any air to enter the tube. WebBarometric pressure is measured with either a mercury barometer or an aneroid barometer. Discover why mercury barometers are often used in laboratories with help …
