What is an aneroid barometer?

An aneroid barometer measures changes in atmospheric pressure through the expansion and contraction of a sealed internal metal box. This mechanism removes the need for liquid mercury columns. Invented in the nineteenth century, these domestic instruments allowed households to track impending weather changes safely upon interior walls.

How do I hang a wall barometer?

These wooden instruments hang securely from sturdy wall fixtures using the designated hanging loops or brackets built into the rear of the timber frame. Ensure the chosen wall position remains free from direct heat sources and heavy vibrations to protect the delicate internal mechanism. Once mounted, gentle calibration using the adjustment screw aligns the needle with local meteorological conditions.

Did these barometers include thermometers?

Many examples on this page combine an aneroid barometer dial with an integrated vertical thermometer mounted into the upper stem of the wooden frame. This dual arrangement provided households with simultaneous temperature and barometric readings. Some more complex variants also housed clock movements alongside the weather instruments.
