Light, strong, and durable, the brass Endurance II 135 Barometer/Thermometer is a combination instrument that conveniently melds barometric pressure and temperature in one location. The barometer at the top of the generously sized dial is a holosteric, or aneroid type, which measures atmospheric pressures mechanically without the use of liquids. The movement is temperature compensated, fully adjustable with inch and millibar scales, and is calibrated for altitudes up to 3,500 feet above sea level. The thermometer in the lower portion of the dial displays both Fahrenheit and Celsius scales. This porthole-style instrument is weather-resistant and guaranteed to never tarnish.
