a device for measuring atmospheric pressure, often specially calibrated for use as an altimeter, consisting of a box or chamber partially exhausted of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air.

Scientific definitions for aneroid barometer

aneroid barometer

[ ăn′ə-roid′ ]

A barometer consisting of a thin elastic disk covering a chamber that contains a partial vacuum. High atmospheric pressure pushes against the disk and causes it to bulge inward, while low pressure does not push as hard, allowing the disk to bulge outward. An aneroid barometer is smaller and more portable than a mercury barometer and, when used with a barograph, can record up to a week's worth of data. Aneroid barometers are used extensively in aviation as part of altimeters.
