Model 410-D - Weems & Plath Deluxe Dampened Barograph
This beautiful German made Model 410-D Weems & Plath Deluxe 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 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, one felt tip pen, and dampening fluid.
