Clegg impact soil tester - Model CIST/882
The Clegg Impact Soil Tester model CIST/882
for measuring and controlling soil strength and consolidation levels.
A known mass, the Clegg Hammer, is dropped from a fixed distance and deceleration is measured as the hammer hits the ground. Four successive trials determine the Clegg Impact Value (4.5kg hammer), while the 2.25kg and 0.5kg instruments display in Gravities.
Constructed with a hardened steel hammer inside a durable tube, the Clegg hammer will give you years of reliable, accurate service.
CIST/882/4.5kg 'Standard' hammer
Civil engineering & construction industry standard Clegg hammer for monitoring and measuring surface compaction, re-instatement etc. The 4.5kg standard hammer Clegg provides a compact and reliable instrument for monitoring and controlling the quality of reinstatements while the work is in progress, avoiding the need for re-excavation.
The CIST/882/2.25kg medium hammer was developed for measuring shock attenuation characteristics of the softer, natural and artificial sports surfaces such as horse and dog tracks, equestrian arenas, etc.
The CIST/882/0.5kg light hammer was developed for measuring shock attenuation characteristics of the softer, natural and artificial sports surfaces such as golf greens, cricket pitches, tennis courts, football and rugby pitches.

- The CIST/882/4.5kg 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
- CIST/882/4.5kg/TREND (option) Readout Unit displays readings of Impact Value (IV) and also allows the readout to automatically detect the difference in readings during 5 drops and to warn the operator of a failed re-instatement by displaying ABORT!
- The CIST/882/4.5kg/%CBR (option) Readout Unit displays direct readings in % CBR (california bearing ratio) and also shows the number of times that the hammer has been dropped during each test operation
