Made by Conant Custom Brass, a division of Weems & Plath in Annapolis, the Jeffersonian Rain Gauge uses a mechanical float and lever design to measure up to 5 inches of rain in 1/5 inch increments. This gauge will turn into the wind to ensure an accurate measurement, or may be tightened down to fix its location. Each rain gauge includes two 14 inch brass rods plus a pressure treated wooden stake for a total length of 42 inches, as well as a hanger bolt for optional installation on a post fence or deck rail. Total height with hanger bolt installation is 14 inches.
