Fortin’s Barometer

We offer Fortin’s Barometer. For meteorological purposes and whenever the highest accuracy and reliability are required, the atmospheric pressure is measured by the Mercury Barometer. This type of barometer consists of a glass tube filled with mercury under a vacuum and immersed in a mercury cistern; the length of the mercury column is measured against an external metallic tube, graduated in units of pressure. The instrument is fully mechanical and operates independently from any power supply. The Fortin type is particularly designed for land stations.
