Used primarily in the roading, base course, drainage and re-course/re-in-statement industries, the Clegg Professional is the choice amongst contractors, landscapers and engineers.

One major benefit of the Clegg Professional is the large display,with clear viewing as well as its ability to be removed and be used handheld unit. The readout is clamped to the guide tube and the displayed reading is viewed from the top during use.

The Readout Unit displays readings of Impact Value (IV) and also shows the number of times that the hammer has been dropped during each test operation. Another key feature of the CIST/883 controller is that the inferred %CBR calculated from the drops is displayed.

IV (or CIV) is similar in concept to the CBR (California Bearing Ratio). CIV may be used as an alternative to CBR in both laboratory and field samples.

The Clegg Professional Impact Soil Tester features a durable, very rugged design, suitable for prolonged use in dirty and harsh site environments.

The CIST/883 readout unit is made from high strength alloy that has been proven to last for decades. This model runs on 2 x AA batteries, typically giving up to 12 months operation.

Bluetooth and GPS models of the Clegg Professional are also available upon request.
