Art Deco barograph by C P Goerz. The oak and plated metal Barograph encase with rounded ends. The mechanical eight-day movement is housed in the drum, fitted with a seven-day chart which covers one full rotation of the drum. The ink trace, or barogram, on the recording paper, is a visual record of changes in pressure.
The aneroid barometer mechanism has nine stacked vacuum capsules and utilises a gate suspension, a refinement developed to improve sensitivity.
