The Isco 674 Rain Gauge is a precision instrument that uses a tipping bucket design for accurate rainfall measurement. It has an 8 inch diameter orifice and is factory-calibrated to tip at either 0.01 inch or 0.1 mm of rainfall. With a 674 Rain Gauge connected, an Isco flow meter or sampler will:

• Plot graphs and print reports of rainfall data on the flow meter's built-in printer
• Store rainfall data in internal memory for retrieval and analysis with Isco Flowlink ® Software
• Activate sampling based on rainfall
