Barometer - Wikipedia, the free encyclopedia
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term ch...

Aneroid barometer: a definition from the Arctic Climatology and Meteorology Primer ... Aneroid barometer An instrument for measuring atmospheric pressure. It is constructed on the following principles: an aneroid capsule (Vidie capsule, which is a thin, disk-shaped box or capsule, usually metallic) is partially evacuated of...

Today we have finely constructed mercurial barometers capable of giving very accurate readings. They are costly and they need special care in handling. For general use an easier though less precise means of measurement has been devised - the ANEROID BAROMETER (aneroid = without fluid)

The pressure-sensitive component of an aneroid barometer is a row of flexible, evacuated cells, often made of a beryllium-copper alloy, supported by internal springs. Small changes in atmospheric pressure cause the assembly of cells to expand or contract which, in turn, deflects the pointer of a semicircular gauge.

An aneroid barometer is a barometer that uses a closed container rather than a mercury column to measure air pressure. It works because air pressure always tries to balance itself.
