Tubular soil penetration meter
The pocketable penetration meter is used for determining the resistance of the soil, in undrained
conditions, to the penetration of the instrument.
It is composed of two telescopic cylinders, which contain compression spring, and a tip which penetrates
into the soil.
The instrument’s graduated scale displays the unconfined compressive strength (UCS) in MPa, as derived
from the force required to drive the tool into the groundThe instrument is particulary useful during continuous surveying to classify cohesiv soils.
The resistance measured with the pocketable penetration meter helps to determine the characteristics
of the soil and provides useful information on its shear resistance.
