 The SBS raingauge is the result of over 3 years extensive fieldwork into determining the optimum design for accurate rainfall measurement in all climatic conditions, irrespective of wind speed and type of precipitation (e.g. drizzle or heavy, convective or tropical rain). The unique design and aerodynamic shape of the SBS raingauge increases measurement accuracy by capturing more rainfall than traditionally shaped cylindrical gauges, minimising outsplash and reducing rainfall losses caused by evaporation. The funnel of the gauge is made from 2.5mm thick powder coated aluminium while the base is manufactured in LM6 marine grade aluminium. The gauge can therefore be installed in extremely hostile conditions. A version with internal heaters is also available for cold climate installations. The gauge is compatible with all modern loggers and event recorders including our VF and Hawk series data loggers with optional telemetry. Two reed switches are fitted as standard giving the option of monitoring the gauge on an additional channel if required or alternatively for use as a control output.
