Overview

The RIM-7499-BOM, designed to Australian Bureau of Meteorology requirements, is a professional grade tipping bucket rain gauge with 8” (203mm) diameter collecting funnel and 0.2mm tip. It utilises a cast metal base, spun copper collecting funnel with machined gunmetal rim and gold plated tipping bucket to provide a proven accuracy of /- 1% at rainfall intensities up to 250mm per hour and /- 3% at rates up to 500mm per hour. Can be ground mounted or mounted on galvanised pipe using Campbell Scientific’s CM240 rain gauge mount. Other bucket sizes are available on request.
