Wall Mounted Weather Instrument
A wall mounted weather instrument reads the atmosphere from your hallway, bringing practical science and rich timber grain together on the panel.
Wall Mounted Weather Instrument
A wall mounted weather instrument takes many forms across our listings, most frequently appearing as mercury stick barometers and carved wood banjo barometers. These pieces track atmospheric pressure, temperature, and time, serving as both scientific tools and decorative fixtures for domestic interiors.
The selection spans several distinct eras, drawing heavily from the Georgian, Victorian, and Edwardian periods. Pieces range from austere London stick barometers housed in mahogany to elaborate Black Forest carved walnut designs.
Makers from provincial towns and capital cities alike signed their names across silvered brass dials and mahogany cases. You encounter instruments designed for domestic halls alongside maritime examples intended for ships' bulkheads.
Markers of quality and execution
Quality rests in the crispness of the brass engraving, the depth and execution of the wood carving, and the fidelity of the maker's signature. Well-executed cases show careful timber selection, balanced proportions, and retained original fittings.
Simpler provincial pieces contrast with signed work by prominent scientific instrument makers, where precision in the scale division and quality of the mechanical movement elevate the piece beyond a mere wall hanging.
Materials across our listings include mahogany, rosewood, oak, walnut, brass, silvered brass, glass, bone, and porcelain.

The Wall Mounted Weather Instrument Glossary
- Stick barometer
- A tall, narrow instrument utilising a vertical glass tube filled with mercury to measure atmospheric pressure against a fixed scale. These represent the earliest common domestic form.
- Banjo barometer
- A domestic instrument housed in a symmetrical wooden case shaped like a banjo, typically combining a circular dial at the top with a mercury tube below.
- Aneroid barometer
- A barometer that measures pressure without liquid, using a flexible metal box that expands or contracts as pressure shifts.
- Barograph
- A self-recording meteorological instrument that draws a continuous line of atmospheric pressure onto a revolving paper drum.
- Silvered brass
- A brass plate treated with a silver solution to create a bright, matte surface suitable for fine black engraving.
- Bulkhead clock
- A marine clock designed to be mounted directly to the wall or bulkhead of a ship, often paired with a matching barometer.
Wall Mounted Weather Instrument: Frequently Asked Questions
How do I read a stick barometer?
Observe the height of the mercury column inside the glass tube against the engraved scale. Rising mercury generally indicates improving weather conditions, while falling levels point towards approaching rain or wind.
Most instruments feature a movable vernier pointer set by hand to track movement since your last check. Comparing the current mercury level to this marker shows the trend of the pressure.
Where should I hang a barometer?
Select an interior wall away from direct sunlight, radiators, and exterior doors. Sudden temperature changes alter the internal air and mercury volume, which disrupts accurate atmospheric readings.
A stable hallway or study provides the ideal environment to keep the timber case and internal mechanism safe from extreme humidity shifts.
How do I tell an aneroid from a mercury barometer?
Look for the visible glass tube containing a pool of mercury at the base, which defines traditional stick barometers. Aneroid models rely on a sealed internal metal capsule rather than liquid.
Aneroid instruments usually display their findings on a large, circular dial marked with weather descriptions like 'Stormy' or 'Fair', rather than a vertical sliding scale.
Are these instruments still accurate?
Many vintage barometers retain functional movements and respond reliably to local weather shifts. However, historic instruments serve primarily as decorative antiques rather than precision meteorological tools.
You can calibrate most aneroid models using a small screw on the back against a known local broadcast reading, though older mercurial tubes require specialist handling.
