Barographs are recording barometers that chart the data over a period of time.
This German made barograph uses an eight diaphragm bellows to provide maximum sensitivity and precision. The rich mahogany and polished brass hinged case provides easy access to the chart drum.
The single "AA" battery operated quartz movement requires no winding and is more accurate than key wound movements. The conventional ink nib and messy ink bottle are replaced by a felt tip pen which lasts 6 to 9 months.
The barograph is furnished with a one-year supply of weekly charts, AA battery, felt tip pen, and dampening fluid.
