For sailors, the barometer remains synonymous with the weather. Indeed, pressure variations announce weather changes. If the barometer drops, a low pressure system is coming and the bad weather it brings. The more sudden the drop, the deeper the low pressure will be, the stronger the wind will be. For those who like to take measurements, following the evolution of the barometer is a daily pleasure. Provided you have a quality device.
The barometer is a mechanical instrument. It works from a capsule of which a partial vacuum has been created before closing it hermetically. The variation of the pressure increases or decreases the thickness of the capsule which then makes the needle of the barometer evolve. The capsule "lives" according to the pressure.
Barometers using this capsule system are called "aneroid". The invention dates back to 1854. Until then, barometers used a long column of mercury to measure pressure variations. The Naudet company was founded in 1860. Today it is the last French manufacturer of aneroid barometers.
The Parisian manufacturer Naudet produces all the parts of the barometer. There is a real know-how in this company, which in the good old days had up to 80 employees. Today, despite the appearance of electronic barometers, the technical skill is still in the hands of the employees who concentrate on the manufacture of beautiful high-end movements. Some of these products are even intended for scientific and military use.
If you have an old barometer that no longer works, Naudet can also repair it and provide all the necessary accessories: paper, ink, spare parts, etc. Their manufacturing workshop located in the Paris region can be visited.
And to diversify the range, we see appearing in the Naudet catalog clocks, thermometers, hygrometers, but also clocks of tides or moon phases. What to associate with its barometer.
Whether in the form of a wall-mounted model (round dial fixed on a vertical wall) or as a barograph (with a stylus that records the pressure), the barometer remains a living instrument that offers the daily pleasure of "making" its weather forecast. Let yourself be tempted.
