Clegg Soil Impact Tester 9.1kg

The Clegg Hammer ( also called the Clegg Impact Soil Tester) consists of a compaction hammer operating within a vertical guide tube. When the hammer strikes the soil surface, a precision accelerometer mounted on the hammer feeds its output to a digital readout unit. The unit registers the dedeleration in units of Impact Value (IV). The IV relates to soil strength and correlates with California Bearing Ratio (CBR) values. An ASTAM standard covers the determination of the Impact Value (IV) of the soil.
