Soil Heavy Duty Pocket Penetrometer

The pocket penetrometer is a world-wide known instrument.
It is used by geotechnicians, geologists, agronomists, etc. to obtain quickly and
easily an approximate measure of the shear resistance at failure of cohesive and
semicohesive soils.

Soil Heavy Duty Pocket Penetrometer

The body of the 16-T0163 pocket penetrometer consists of two telescopic
cylinders containing a compression spring. A cylindrical tip, screwed at the lower part
of the body, is pushed into the soil compressing the spring.
The 16-T0163 penetrometer is suitable for severe environmetal conditions. The
complete instrument, including the spring, is made of stainless steel.
The 16-T0163 has been designed to allow relatively deep penetration of the soil
for a pocket penetrometer (up to 6 cm max); this reduces mistakes and uncertainties
typical of shallow measures which are often affected by remoulding, drying, etc. of
the surface.
A value of the unconfined compressive strength (UCS) can be directly read from
the scale on the instrument. This value (see appendix) has been derived from the so
called "point resistance" which is the force needed to penetrate into the soil.
Measured strength values can assist the classification and description of
cohesive soils and also give useful preliminary information about the shear strength.
The 16-T0163 can be used both in the field and in the laboratory with soils
having UCS values (unconfined compressive strength) between zero and 2 MPa. For
soft to medium soils the use of the largest tip is recommended to obtain a good
resolution.
