Where should I hang a wooden wheel barometer?

Hang the instrument on an interior wall away from direct sunlight, central heating radiators, and damp draughts. Sudden temperature swings can affect the wood and the movement of the internal mercury. Ensure the wall fixing is secure, as these hardwood cases carry considerable weight from the glass and mercury components.

How do I date a wooden wheel barometer?

Examine the shape of the wooden case, the style of the dial engraving, and any signature belonging to the maker. Regency models often feature simpler mahogany outlines, while Victorian versions introduce carved walnut and elaborate mother-of-pearl inlay. Makers frequently recorded their working towns on the brass dial face, which helps cross-reference historical trade directories.

Are these barometers still accurate?

Many nineteenth-century mercury barometers remain mechanically sound and respond accurately to changes in air pressure. The internal glass tube and cistern must remain intact and filled with clean mercury for proper function. They serve as working scientific instruments alongside their role as decorative wall pieces in period interiors.
