Jeffersonian Drum Thermometer

Inspired by Thomas Jefferson's affinity for invention, this unique thermometer uses a large, protected bimetal coil that provides an accurate reading, even in full sunlight. As the bimetal coil expands with warmer temperatures and contracts with colder temperatures, the coil causes the brass drum to turn until the large numbers align with the aluminum pointer to indicate the current temperature in degrees Fahrenheit. The Jeffersonian Drum Thermometer is made of solid brass and aluminum. Within a few months exposure to the elements, the brass finish will begin to age gracefully and develop a mellow patina. This aging process is what we call “Living Finish Brass.”
