Catalog excerpts

The Isco 674 Rain Gauge is a precision instrument that uses a tipping bucket design for 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: Store rainfall data in internal memory for retrieval and analysis with Isco Flowlink® Software Activate sampling based on rainfall Plot graphs and print reports of rainfall data on the flow meter’s built-in printer Applications Stormwater runoff monitoring TMDL and Watershed surveys Inflow and infiltration studies cMOM and CSO/SSO programs (Sewer overflow monitoring and prevention) General rainfall measurement Standard Features Three-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. The 674 rain gauge features a precision tipping bucket and 3-point leveling system for easy setup. Isco 674 Rain Gauge Connects directly to 6712 and Avalanche™ Samplers, 4200 Flow Meters, and 4100 Flow Loggers A 674 rain gauge connected to an Isco 6712 or Avalanche sampler is ideal for collecting rainfall data as well as runoff-triggered samples at remote monitoring sites.
