Product Description

A very fine quality and attractive looking Mahogany glazed Comitti display Barograph with an internal drawer, that holds spare drum paper sheets and a bottle of ink.

The barograph is built of gilded brass mechanism with an 8 ring vacuum stack, which distorts with the fluctuations of air pressure. This is connected an articulated arm to a rotating drum which holds the barograph chart. The drum turns on a wind-up mechanism and the chart covers a whole week (1 rotation). This allows the viewer to see a record of the barometric variations over a period of time. Hence the difference between a barograph and a barometer.

Condition is very near mint.

In 1850 Onorato Comitti, an Italian precision instrument maker, opened his workshop in Clerkenwell, London. In a very short time he gained a reputation for superb workmanship and in 1888 the company was acknowledged with a Diploma of Honour as one of the finest barometer and clockmakers in England.
