Dampened Deluxe Quartz Barograph:
The German made Dampened Deluxe Quartz barograph uses eight diaphragm bellows to provide maximum sensitivity and precision. The 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 inkbottle are replaced by a felt tip pen, which lasts 6 to 9 months.
This barograph is furnished with a one-year supply of weekly charts, AA battery, and one felt tip pen and dampening fluid. A superb way to keep precise records of barometric pressure readings is with the elegant German-made Dampened Deluxe Quartz Barograph which uses eight diaphragm bellows to provide maximum sensitivity and precision.
