4.5 Kg Hammer Model Type CIST/883 (Data Logging & Bluetooth)
The 4.5 Kg CIST/883 Clegg Impact Soil Tester manufactured by SDi provides an easy and straightforward means for measuring and controlling soil strength and consolidation levels during trench re-instatement. The 883 readout is clamped to the guide tube and the displayed reading is viewed from the top during use. Single button operation design provided for easy use.

Data Logging Feature
On board data logging and data storage with wireless data transfer facilities are features provided with the CIST/883 instrument. Users can download their test results from site to PC, wirelessly, using the PC software supplied with the instrument. This cable-free operation greatly enhances system reliability compared to cabled systems.
The instrument is used to confirm uniform compaction of over wide areas of ground, identifying poorly compacted areas and ineffective rolling of materials.
The CIST/883 Clegg Impact Soil Tester is a very rugged design suitable for prolonged use in damp, dirty and harsh site environments. The CIST/883 readout unit is made from high strength alloy that has been proven to last for decades. The CIST/883 battery compartment, sealed to IP67, is fitted with 2 x AA batteries for typically 12 months operation. The CIST/883 Clegg Impact Soil Tester is a compact and reliable instrument. A wooden Transit & Storage Case is included.
The Tester consists of a 4.5 kg compaction hammer operating within a vertical guide tube. The Hammer falls through the tube when released and strikes the surface under test, decelerating at a rate determined by the stiffness of the material within the region of impact. The readout registers the deceleration in units of Impact Value (IV). The IV is an indication of soil strength.
Good correlation with results from CBR tests exists. Data from the CIST/883 can be used in a similar manner to results from CBR tests performed in the laboratory and in the field. The CIST/883 display can directly show the %CBR result based upon Dr Clegg’s original pioneering work. This feature is simply selected from the PC software provided.
