Weems & Plath's Endurance Collection combines precision instrumentation with classic design. The result is an instrument you would be equally proud to display or give. The barometer uses a highly accurate, temperature compensated aneroid movement with inch and metric scales. One of the more unique features of the Endurance line is the slide-on mounting system that make adjustments a breeze. It also features a brass case guaranteed never to tarnish. It measures 6" at the base and 1 5/8" thick. The beveled glass crystal is 4 7/8" in diameter.
