Brass Pressure Gauge
These brass pressure gauge pieces combine industrial function with period craftsmanship, offering a distinct focal point for any interior.
Brass Pressure Gauge
When you search for a brass pressure gauge, you encounter scientific instruments and barometers originating from the Victorian, Edwardian, and early twentieth-century periods. These items encompass wall barometers, barographs with chart drawers, aneroid barometers, and specialised industrial water pressure gauges.
The versions most frequently met on this page include mahogany and walnut cased barographs alongside wall-mounted instruments framed in ebonised wood or Black Forest carved timber. Makers such as Short & Mason, Dewrance of London, and Dollond represent the origin of these domestic and industrial recording devices.
How they were made
Construction relies heavily on heavy cast brass housings combined with turned timber cases fashioned from mahogany, walnut, and ebonised wood. Enamel dials feature crisp black graduations beneath protective glass bezels, while specialised scientific pieces incorporate delicate steel and ceramic components.
Makers housed sensitive aneroid movements inside robust wooden cabinetry, often integrating lower chart drawers for continuous meteorological recording. Carved Black Forest woodwork demonstrates regional craftsmanship applied to functional scientific housing.
Some models feature lower chart drawers designed to hold paper records, turning atmospheric data collection into a tidy desk accessory.
What varies in quality
Quality rests upon the crispness of the enamel dial markings and the mechanical refinement of the internal barometer or gauge movement. Heavy cast brass bezels with patinated surfaces contrast with lighter, plain metal fittings.
Cabinetry execution separates standard production items from superior examples, particularly where figured walnut, rich mahogany, or detailed Black Forest carvings are employed. Signed dials bearing recognised London makers add a layer of distinction to the overall piece.

The Brass Pressure Gauge Glossary
- Aneroid barometer
- An instrument measuring atmospheric pressure without liquid, utilising a flexible metal box that expands or contracts.
- Barograph
- A recording barometer that plots atmospheric pressure over time onto a paper chart housed in a drawer.
- Ebonised wood
- Timber treated with a finish to imitate expensive ebony, frequently utilised for Victorian scientific instrument frames.
- Fortin stick barometer

Brass Pressure Gauge: Frequently Asked Questions
What is a brass pressure gauge used for?
These instruments were originally engineered to measure atmospheric pressure, industrial water pressure, or altitude within domestic and workplace settings.
Today, buyers primarily utilise them as decorative wall pieces or desktop conversation objects that reflect historical engineering.
How do I identify a Victorian barometer?
Victorian examples typically display heavy timber framing in mahogany or ebonised wood, paired with detailed enamel dials and brass bezels.
Signed dials bearing nineteenth-century London makers provide clear attribution to this period of manufacture.
Where should I place a barograph?
A barograph requires a stable surface away from direct heat sources and heavy vibrations to ensure the timber case remains protected.
Placement on a sturdy desk or bookshelf allows the glass cover and chart drawer to be easily viewed.
What is the difference between an aneroid and a stick barometer?
An aneroid barometer uses an internal sealed metal capsule to indicate pressure changes without employing liquid columns.
A stick barometer relies on a vertical glass tube filled with mercury to measure atmospheric fluctuations directly.
