Key Differences. Barometers are instruments primarily used for meteorological purposes, measuring atmospheric pressure to predict weather changes. Manometers, conversely, are used to measure the pressure of gases or liquids in various applications, including industrial and scientific settings. The design of barometers …Barometer is a device for monitoring atmospheric pressure, primarily used for weather forecasting and altitude calculations. It is used to gauge air pressure as it changes with altitude, either above or below sea level. It was created in 1643 by the Italian scientist E. Torricelli.Barometers using mercury are heavy and fragile. The idea of a "dry" barometer was conceived by Gottfried Wilhelm Leibniz around 1700. It would be a way to detect pressure changes using sealed bellows. The first working version of an aneroid (without water) barometer was built in 1843 by French scientist Lucien Vidie.

What is an Aneroid Barometer? An aneroid barometer is a type of instrument used to measure atmospheric pressure. The name “aneroid” comes from the Greek words “a-” meaning ‘without’ and “nēros” meaning ‘liquid’. This name came about because all previous barometers used either mercury or water to measure changes in pressure.

Barometers. Barometers are instruments that measure the pressure of air in a specific environment; barometer measurements are used to forecast weather and measure altitude. Atmospheric pressure also depends on the planet’s mass, its surface radius, the gas concentrations and composition, and the gases’ vertical distribution in the atmosphere.A barometer measures pressure. A barometer is used by meteorologists. Different types of barometers have been developed and used at different historical periods. Barometers traditionally produced ...The barometer’s needle pointed to “fair,” indicating stable weather conditions for the next few days. By observing the barometer’s readings, the sailor could anticipate the approaching storm.
