The tipping bucket rain gauge is recognized as the standard for measuring rainfall and precipitation in remote and unattended locations.

The integrated siphon mechanism delivers high levels of accuracy across a broad range of rainfall intensities. Each unit consists of a collector funnel with stainless steel leaf filter, an integrated siphon control mechanism, an outer enclosure with quick release fasteners, and base which houses the tipping bucket mechanism. The unit includes dual output reed switches with varistor protection (helps shield sensitive components against excessive transient voltage) as well as dual rainfall discharge outlets for water collection and/or analysis.

The bucket tips when precipitation of 0.01 inch, 0.2mm, 0.5mm or 1.0mm has been collected. Each tip activates a reed switch closure which is detected by a data logger and/or telemetry system.

Stevens also offers an expanded catch tipping buckets rain gage with a larger catch size, measuring 1
