Weems & Plath Endurance II 115 Barometer & Thermometer
Light, strong and durable, the brass Endurance II 115 Barometer/Thermometer is a two-in-one instrument that conveniently combines barometric pressure and temperature gauges in one location. The barometer at the top of the dial is a holosteric or aneroid type which measures atmospheric pressure mechanically without the use of liquids. The open movement is temperature compensated, fully adjustable with inch and millibar scales and is calibrated for altitudes to 3,500 feet above sea level. The thermometer in the lower portion of the dial displays both Fahrenheit and Celsius scales. This midsize front opening porthole style instrument is weather resistant and is guaranteed to never tarnish.
