RIM7499

Professional Grade Tipping Bucket Rain Gauge

The RIM7499, 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.


Features

  • dual reed switch
  • built-in bubble level
  • low friction, non-seizing bearings
  • rugged, corrosion resistant construction.

Can be ground mounted or mounted on galvanised pipe using Campbell Scientific’s CM240 rain gauge mount. Other bucket sizes are available on request.
