📖 An era of color and genius: mechanical barometers, also known as aneroid chambers, are commonly used to measure atmospheric pressure through the use of liquids. Invented in 1843 by the Frenchman Lucien Vidi, these devices offer a practical and portable alternative to Mercury barometers.

The heart of a mechanical barometer is a sealed metal capsule, called an aeroid capsule, inside which a partial vacuum has been created. Variations in the external atmospheric pressure cause the deformation of the capsule: when the pressure increases, the capsule compresses; When you disminuye, you expand. These movements are amplified by a system of poles and gears that move a needle on a classification dial, which indicates the value of the atmospheric pressure. Unlike mercury bars, mechanical barometers do not contain toxic substances, which makes them safer and easier to handle.

• Portability: thanks to their compact structure, they are ideal for use on domestic, nautical and leisure excursions.

• Ease of reading: the analogue dial allows immediate reading of the atmospheric pressure.

• Durability over time: the robust construction and the absence of electronic components make the products long-lasting and reliable.
