Weems & Plath Classic Barograph

Record barometric pressure with this mechanical German-made Classic Barograph that measures variation in air pressure and transfers the data through a system of mechanical levers to the writing arm. Housed in a rich mahogany case with glass sides and a polished brass handle, this barograph is equipped with a battery operated quartz movement with 4 diaphragms that rotates the solid brass drum once a week, requires no winding, and is more accurate than key wound movements. The barograph readings are marked on paper charts with a felt tip pen.
