Lightweight penetrometer

The device is used to mea­su­re the pene­tra­ti­on resis­tance in geo­tech­ni­cal inves­ti­ga­ti­ons. In dyna­mic pro­bing, the pro­bing rod with a pre-screwed, defi­ned impact point is driven into the sub­sur­face by the drop weight with pre-defi­ned fal­ling height. During this pro­cess, the pene­tra­ti­on depth and the number of impacts are recor­ded. 

Dyna­mic pro­bing tests can be con­duc­ted quick­ly and are sui­ta­ble for a gene­ral assess­ment of the subsurface´s strength.

The advan­ta­ges of the light­weight pene­tro­me­ter lie in its robust con­s­truc­tion and the abili­ty for one person to ope­ra­te it.
