Antique Brass Holosteric Barometer

Antique Brass Holosteric Barometer - Melvin-White Co. (Boston & New York)
Late 1800s – Early 1900s

A beautiful nautical brass barometer produced by Melvin-White Co., a maker of maritime instruments serving the busy port cities of Boston and New York during the late 19th and early 20th centuries.

This holosteric (aneroid) barometer measures air pressure using a sealed metal chamber that expands and contracts with atmospheric changes—an innovation that eliminated the need for liquid mercury and made these instruments safer and more practical aboard ships.

The solid brass casing and original maker’s label give this piece wonderful maritime character. Though the instrument is non-functional and the glass has a visible crack, it remains a striking decorative object with authentic nautical history. Perfect for coastal interiors, libraries, studies, or anyone drawn to the romance of maritime exploration.
