Commercial Grade Rain Gauge

Campbell Scientific

 The RIM8000 series is a commercial grade rain gauge that uses the same tipping bucket and siphon assembly as the RIM7499 series but with a spun aluminium base and a spun copper collecting funnel and rim. The RIM8000 is accurate to within /- 3% at intensities up to 380mm per hour and /- 5% 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.
