The Jeffersonian Rain Gauge is a practical instrument that also beautifies your outdoor space. Inspired by Thomas Jefferson’s flair for invention, this unique device uses a float and lever design to measure up to 7” of rain in 0.2” increments. As rain fills the vial, the red ball rises, causing the steel arm to climb up the scale. This updated model features a more durable design and includes a solid steel deck mount and foundation rod.
