wall metal barometer

This metal wall barometer is a meteorological instrument that allows you to measure the atmospheric pressure of a given environment.

It consists of a flexible metallic diaphragm, which integrates a small amount of air inside it inside a hermetically closed metal chamber. When pressure increases, this chamber compresses. In turn, when the pressure decreases, it expands. This change is felt by the barometer hands that move according to the received information.

The barometer is an instrument widely used in meteorological stations and on board ships.
