Próbnik Osterberga
It’s an Osterberg infixion sampler suitable for sampling of silt, clay and granular
soils of medium-fine grain.
It allows to take high quality undisturbed samples and larger in diameter than the
ordinary Ostrberg sampler (88.9 mm). The outer diameter of the overlapped
Osterberg sampler (101 mm) is the same of the sampling tube diameter.
