DESCRIPTION

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.
