 | | The aneroid capsule, which is the device that moves with changes in air pressure, is made from an alloy of beryllium and copper. |
 | | By arranging for the aneroid capsule to push or pull on a point near the pivot of a see-saw-like lever, the movement of the capsule is greatly magnified at the far end of the lever. |
 | | All aneroid barometers come with a zeroing screw to adjust the initial position of the sweep indicator to be the same barometric pressure as that of a very precise standard barometer kept at the factory. |
