Connects directly to 6712, BLZZRD, and Avalanche Samplers, 4200 Flowmeters, and 4100 Flow Loggers
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
-
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.
MAIN APPLICATIONS
-
Stormwater runoff monitoring
-
Inflow and infiltration studies
-
Combined sewer overflow monitoring
-
CMOM and CSO/SSO programs (Sewer overflow monitoring and prevention)
-
General rainfall measurement
OPTIONS & ACCESSORIES
-
English units – tips every 0.01 in. of rainfall
-
Metric units – tips every 0.1 mm of rainfall
