High Accuracy Tipping Bucket Raingauge
The Hydrological Services Tipping Bucket Raingauge is recognized as the world standard for measuring rainfall and precipitation in remote and unattended locations.
The integrated syphon mechanism delivers high levels of accuracy across a broad range of rainfall intensities.
Each unit consists of a collector funnel with leaf filter, an integrated syphon 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 as well as dual rainfall discharge outlets for water collection and/or analysis.
