Vermont Outdoor Thermometer by Conant Custom Brass
Non-mercury Outdoor Thermometer
In fact, no mercury thermometers are made anywhere in the USA. Non- mercury thermometers, such as our spirit thermometers, use pigmented mineral spirits which have proven to be just as accurate as mercury thermometers. Mineral spirits include a variety of compounds, and are derived from light distillate fractions from the crude oil refining process. Spirit gauge thermometers rely on the principle that liquids expand when they are heated and contract when they are cooled. This type of thermometer consists of a reservoir for the liquid, the bulb, connected to a very narrow tube. The narrow tube accentuates the very small changes in the liquid\'s volume that occur when the temperature of the liquid changes. These thermometers are accurate to within +1/-1 degree.
All of Conant Custom Brass spirit thermometers are 100% made in the USA.
