U.S. Weather Bureau Type Rain & Snow Gauge

For professionally accurate rainfall measurements. This all-aluminum gauge has a total capacity of 20” of rainfall and is graduated in inches, 10ths, 100ths, cm, and mm. The upper portion of the funnel is cylindrical in shape and is turned to a sharp edge. Rainwater falling into the funnel is delivered into the anodized aluminum receiver. The ratio of the area of the orifice to the area of the receiver is 10:1, so that 1” of rainfall delivers 10” of water to the receiver and can be read to 0.01”. The capacity of the receiver is 2” of rainfall. Any excess overflows into the outer chamber where it can be measured after the quantity in the receiver has been removed using the funnel. When used as a snow gauge, the receiver and funnel are detached and snowfall is measured directly. Furnished with black lamacoid measuring stick. Tripod sold separately. 8-1/4” Dia. x 27”H overall.
