Teledyne Isco 674 Rain Gauge

DESCRIPTION

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 rainfallStandard FeaturesThree-point leveling and integral bubble level make it easy to align the rain gauge for maximum accuracy.Sapphire jewel bearings on the tipping bucket are spring-loaded to prevent damage to the bearings and ensure consistent operation over a wide temperature range.Screens cover all openings to prevent leaves, insects, and other debris from clogging the gauge.Included 50-foot cable connects directly to compatible Isco flow meters and samplers.
