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 Comfortmeter combines a thermometer and hygrometer and indicates a "comfort zone" where the two needles intersect. One of the more unique features of the Endurance line is the slide-on mounting system that makes mounting a breeze. Measuring 6" at the base and 1 5/8" thick the brass case has an ultra hard finish guaranteed never to tarnish. The beveled glass crystal is 4 7/8" in diameter.
