AI-assisted summary
Description from the seller
An antique industrial recording device (Thermo, graph, barograph or manograph) manufactured by the famous Italian company Spriano Milano. Founded in Milan in 1923 by Guido Spriano. The brand has become a historical benchmark in the design of measuring instruments.
The left side of the device houses a mechanical cylinder, equipped with a sheet of squared paper; the drum turns slowly, thanks to an internal clockwork mechanism (operates).
The two horizontal hands rub against the paper to continuously trace the evolution of a measurement such as pressure or temperature over the hours or days.
The right side is fitted with a decorative geometric grid in a honeycomb pattern. This allowed air to circulate freely.
Today, these pieces of Spriano’s worthy engineering are magnificent vintage collectibles.
Note: the mechanism works, but will still need servicing.
