Barometer - Wikipedia
Barometer. A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.

Predict the type of weather near you by watching a barometer. As discussed, a barometer is a type of instrument that measures air pressure. Low pressure usually means rainy weather, while high pressure means mild cool weather.
What is an aneroid barometer ? Draw a neat and labelled diagram …
A barometer calibrated to read directly the atmospheric pressure is called an aneroid barometer. It has no liquid, it is light and portable. Construction: Figure above shows the main parts of an aneroid barometer. It consists of a metallic box B which is partially evacuated.

A barometer is a scientific device that is useful to measure air pressure in a given environment. The barometer is the instrument uses to measure the air pressure as it varies with the distance either above or below the sea level.
Barometer & Atmospheric Pressure - Mini Physics
A barometer is a simple instrument for measuring atmospheric pressure. A barometer can be made by filling up a long glass tube with mercury, then turning it upside down in a bath of mercury as shown. The space at the top of the barometer tube is a vacuum and exerts no pressure on the mercury column.
