Not only functional, the Jeffersonian Rain Gauge offers the owner an artistic embellishment to a favored garden retreat. Inspired by Thomas Jefferson's notable prowess for mechanical invention, the Jeffersonian Rain Gauge uses a mechanical float and lever design to measure up to 5" of rain in 1/5" increments. This gauge will turn into the wind to ensure the most accurate measurement or may be tightened down to fix its location. Made from solid brass, glass and stainless steel, and Guaranteed for Life! Included with the Jeffersonian Rain Gauge is a pressure treated wooden stake for ground installation, as well as a hanger bolt for mounting on a post, fence or deck rail.
