The NWS Type Rain and Snow Gage is an all aluminum rain and snow gage with a total capacity of 20" of rainfall. The upper portion of the funnel is cylindrical in shape and is turned to a sharp edge. Rainwater falling into the funnel is delivered to the receiver in a 10 to 1 ratio so that 1" of rainfall delivers 10" of water to the receiver. Gage can be read to 0.01" with a 2" capacity in the receiver and any excess overflows into the outer chamber where it is also measured.
To use as a snow gage, the receiver and funnel is removed to directly measure snowfall. Includes a measuring stick with English and metric units and a tripod is sold separately. The orifice is 8"; capacity: 20"; size: 8" x 27" and resolution: 0.01" (0.25mm)
