For sale a Victorian brass cased aneroid barometer by Negretti & Zambra London.

This early example has a five inch silvered dial engraved with Vidi type weather indications and a scale measuring 28 to 31 inches of barometric pressure to the upper half. The lower part of the dial has a curved thermometer with scale for 0 to 120 Fahrenheit and the maker’s name Negretti & Zambra, London and the serial numbers of 1060. It has a blue steel pointer and a brass set hand operated by a brass knurled dial to the centre.

The piece comes complete with its origina hanging loop and adjustments for elevation can be made by means of a screw at the back of the instrument.

Negretti & Zambra were a leading name in the production of meteorological and scientific instruments and had a company history dating back to 1850 although their parents were amongst those Italian emigres that bolstered the British meteorological instrument making industry at the turn of the century.

Throughout their long and esteemed history they exhibited at British and international industrial fairs and became makers to both Queen Victoria and Edward VII. Owing to changes in the business, the firm ceased the public retailing of scientific instruments sometime around the late 1960’s and continued with a focus on the aviation industry in numerous guises until its eventual liquidation in the year 2000. They are today perhaps the most collected of the scientific instrument firms which bears testament to the quality of their work.

A great example of its type with an early serial number. Circa 1855.
