Isco 674 Rain Gauge Survey Both models of the TSP

Both models of the TSP (total suspended particulate) high volume sampler meet EPA requirements for a flow rate between 39 and 60 cfm

Suppose problems occur due to liner reflections that don't come to the top of the casing or unwanted signal returns from such things as pitless adaptors that interfere with getting a proper reading

An impact body with a hard metal test tip is propelled by spring force against the surface of the test piece

Isco 674 Rain Gauge Survey Both models of the TSPThe 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
