Description
Overview
GAOTek tipping bucket rain gauge with UV protection and RS485 is a durable weather instrument for monitoring rain rate and total rainfall. It has been updated and improved with the addition of an inner funnel to even the flow of the rainfall into the gauge, providing better accuracy at higher rainfall rates. With minimal care it will provide many years of service. The rain gauge is constructed of high impact UV-protected plastic/ stainless steel to provide reliable, low-cost tipping bucket rainfall monitoring. The tipping bucket sensor mechanism activates a sealed reed switch that produces a contact closure for each 0.1mm, 0.2 mm or 0.5mm of rainfall. The rain gauge sensor can be pole mounted or bolted to a level plate.
