Technical description:

It consists of a thermal imager and a hygrograph. The temperature sensitive element is a bimetallic strip ring whose operational characteristics are a low coefficient of delay and resistance to environment. This device controls through appropriate levers a stylus. It is adjustable with a screw and is protected against accidental knocks. The hygrometer has a sensor element consisting of a hair bundle that, depending on the relative humidity varies in length. The change commands, through a system of levers, another stylus. The device has a protection for the hair bundle, a cylindrical cage that slides for maintenance.
The drum contains the clock components, to be charged weekly. Case in painted metal with 2 lights (with glass), with handle on the top of the instrument, it’s hinged on the frame, allowing the extraction of the drum to change the plotted sheet and to charge the clock spring that’s contained in it.
