This Professional Rain Gauge, a precision weather instrument, was developed and manufactured to specifications from the U.S. Weather Bureau. The top funnel of the instrument catches rain and delivers it to the one-inch capacity measuring tube, which can read to the nearest 1/100th of an inch. When the measuring tube is full, additional rain overflows into the outer cylinder. Pour the rain water from the outer cylinder into the measuring tube, and you read the amount of rain you have received, up to eleven inches.
By using only the outer cylinder you can gather and measure content of solid precipitation. Melt snow or hail and use the measuring tube to determine the water content accurately and quickly.
The Professional Rain Gauge comes complete with no-rust mounting bracket, installation instructions, and full instructions on how to use it, as well as a one-year diary for recording rainfall.
