This is a cased barograph with a drawer for storing spare charts and instructions. The instrument features a brass mechanism with a series of aneroid capsules that respond to changes in atmospheric pressure. This movement is linked to a pen arm, which records the pressure variations on a chart attached to a rotating drum. The base is wooden with a mahogany finish and the instrument is protected by a glass case. There are instructions included. Untested. Sold as seen.
