The Teledyne 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, a Teledyne ISCO flowmeter or sampler will:
- Plot graphs and print reports of rainfall data on the flowmeter’s built-in printer
- Store rainfall data in internal memory for retrieval and analysis with Teledyne ISCO Flowlink® Software
- Activate sampling based on rainfall
- STANDARD FEATURES
- MAIN APPLICATIONS
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 Teledyne ISCO flowmeters and samplers.
