Comitti published a broadsheet showing registered patents and a comprehensive collection of mercury and aneroid weather instruments. Barometers for marine use, Admirals Fitzroy’s instruments designed for recording data across Britain for coastal and national forecasting, Fortin barometers for scientific research, Pocket Aneroid for altitude measurement, the company’s Improved Torricelli Barometer, sophisticated Royal Polytechnic Barometers, recording Barographs and mantel barometers including timepiece movements.

Comitti of London are the oldest barometer makers in the world. The roots of the company’s instrument making skills can be traced back to Evangelista Torricelli who made the first mercurial barometer in 1643, although the principle of the instrument was described in 1630 by Galileo Galilei.The aneroid barometer was invented in 1844 by French scientist Lucien Vidi and patented in London in 1845. The barometers made by Comitti today reflect this unique heritage and over 160 years experience in making fine instruments. The classic English barometer retains its value as a local weather forecaster, with particular appeal to those who enjoy outdoor leisure activity. In addition, instruments fitted with a hygrometer and thermometer allow for monitoring of the home environment. But perhaps the prime reason that an instrument made by Comitti remains a popular gift and decorative piece for the home is the outstanding workmanship employed in creating them.
