The ISCO rain gauge uses a tipping bucket design to measure rainfall accurately. It is factory calibrated to tip at 0.1mm of rainfall. When an ISCO flowmeter or sampler is connected to the rain gauge it will store rainfall data in its internal memory for retrieval and analysis with ISCO Flowlink Software, plot graphs and print reports using the built in printer and activate sampling based on rainfall.
