The 8" diameter collector meets NWS specifications for statistical accuracy.

Every time the bucket tips, a count is transmitted to the indoor display and the gauge empties. You never have to empty the gauge. Each tip of the bucket shows one hundredth of an inch on the indoor LCD display. The display will store storm totals until reset or aggregate accumulations up to 9.99" of rain.

A button on the counter lets you reset to zero after each rainfall period you choose to measure. Installation to the plug-in counter is a cinch. The long-life alkaline counter battery is included.
