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. The hinged case of this marine barograph 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 convenient felt tip pen which lasts 6 to 9 months.
