High performance, rugged corrosion-resistant construction, and handsome satin-finished mahogany cabinet qualify the Atlantic for use offshore as well as at home. The linkages in this recorder are tight, eliminating the need for marine damping when used at sea. Further, the Atlantic is more compact than other barographs using a weekly chart with as much scale resolution. This level of detail is served dutifully by a sensitive eight cell aneroid sensor. Supplied with 'AA' battery, cartridge felt-tip pen, and 100 weekly charts in your choice of 28.00-31.00 inches or 960-1060 millibars. The Atlantic is our most accurate marine barograph for the dollar. 10 1/2'L x 7 1/2'H x 6 5/8'D.
