📖 Here's a quick guide: the mechanical barometers, also called bartenders, are used to measure atmospheric pressure without using liquids. Invented in 1843 by the Frenchman Lucien Vidi, these devices offer a practical and portable alternative to mercure barometers.

The heart of a mechanical barometer is a metallic capsule, called aeroid capsule, inside which you saw it created. The variations of the external atmospheric pressure cause the deformation of the capsule: as the pressure increases, the capsule compresses; When it decreases, it develops. These movements are amplified by a system of levers and screws that place a needle on a cadran of classification, also indicating the value of the atmospheric pressure. Contrary to the mercure bars, the mechanical barometers do not contain toxic substances, which makes them safer and easier to handle.

• Portability: Thanks to its compact structure, they are ideal for use in the home, at sea and on excursions.

• Facilité de lecture: analogue modules allow an immediate lecture of atmospheric pressure.

• Durée dans le temps: la construction robuste et l’absence de composents électroniques en font des outils longés et fiables.
