Clegg Impact Hammers
There are three 4.5 Kg Clegg Impact Soil Tester versions of the type used for trench re-instatement quality control. Two of them have data logging. All three models use a 4.5 Kg hammer but the recording electronics are different. Brief descriptions of these are given below:- The 4.5 KG CIST/882 (Non Data Logging):-This is the straightforward classic type. The user holds the readout in one hand and carries out the hammer testing with the other. User selection of %Californian Bearing Ration (CBR) is provided. No data logging is provided with this model. The 4.5 Kg CIST/883:-This model has the readout unit clamped to the Guide Tube with a vertical display so the user does not hold the readout when testing. It stores test data in memory against a time and date stamp. Data download to a PC is by Bluetooth and all accessories are provided. User selection of %Californian Bearing Ration (CBR) is provided. The 4.5 Kg CIST/884:-This model has the same data storing, %CBR, Bluetooth and design features of the CIST/883 above but is equipped with integral Global Positioning. The test results are referenced by longitude and latitude fix. It stores a file readable directly by Google maps and Google Earth that shows the test locations as yellow pin placements on a map with the test results alongside. GB Ordnance Survey grid references that are preferred for reporting purposes are produced too, to a resolution of 1 metre. The price each is approximately As a guide for deciding which of the above 4.5 Kg instruments to select, a brief summary is offered as follows:- CIST/882: With this model the readout is held in the hand. It is satisfactory if site test data logging is not required.CIST/883: This unit provides data logging and Bluetooth (if required) and is slightly easier to operate because the readout unit does not require holding.CIST/884: This version has all the CIST/883 features but the CIST/884 fitted with GPS also provides longitude and latitude test location data.
Cone Penetrometer

The Soil Assessment Cone Penetrometer (SACP or MEXE Probe) is a lightweight instrument for rapidly measuring in-depth resistance to penetration, indicating with a dial, in terms of California Bearing Ratio (CBR).
The Mexe probe is a robust and reliable instrument used throughout the world by both commercial and military establishments.
• Measurement range for CBR is from 0-15% CBR.
• Soil trafficability measurements can be made using the Cone Index (CI) range.
• The linear CI range is from 0-300 and has 60 divisions, each of 11.12N (1.13kgf). Full deflection is 667N (67.9kgf).
• Steady penetration of the cone into the soil is required and readings are taken from the dial at 75mm (3”) intervals during penetration to a maximum depth of 600mm (24”).
• In fine-grained soils, for which the SACP is primarily intended, measurements correlate closely with CBR values, measured in-situ with conventional equipment.
• The Mexe probe is supplied complete with carrying case, which contains one CBR cone, one CI cone, one top rod, three extension rods (150mm each), tools and operating instructions.
