What Are the Primary Uses of an Aneroid Barometer?

Aneroid barometers are often used for reading pressure in homes and recreational boats. Other uses may include barographs in meteorology and altimeters in modern aircraft.

Aneroid barometers primarily measure whether pressure is rising or falling. This type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense. There are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level. Another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper. When used in this capacity, the aneroid barometer can store a week’s worth of data.
