Jeffersonian Drum Thermometer - Bimetallic Coil Expands and Contracts
When you buy through links on this site, I may earn a commission.
This cool new Jeffersonian Drum Thermometer from Conant Collections is a unique outdoor thermometer that uses a bimetallic coil that expands or contracts in the hot or cold to turn a numbered brass drum until it aligns with a pointer that shows the current accurate temperature, even in full sunlight. It displays temperatures in Fahrenheit, develops a beautiful patina when exposed to the elements, and optional matching ground and wall mounts are available separately. It's perfect for patios, gardens, or even indoors as an unusual informative curio and makes a cool gift as well.
