Clegg Soil Impact Tester 2.25Kg
Clegg Soil Impact Tester 2.25Kg
The 2.25 kg "Medium" Hammer was initially based on the "standard proctor" 2.5 kg laboratory compaction hammer but evolved to its present weight and drop-height for measuring shock attenuation characteristics of natural and artificial playing surfaces.
It is constructed to be the same size as the Standard Hammer by using a mechanical combination of aluminum and hardened steel for the striking end rather than steel with a hardened steel end as used for the Standard Hammer.
In the GTM style, shipping weight is a bit over 10 kg. Notation for the output is CIV/M when the Medium Hammer is dropped from its standard height of 45 cm.
