pocket penetrometer/Mini Penetrometer
the penetration resistance of top layers (depth 5 mm) and of samples in the field or lab.

 

Pocket Penetrometer/Mini Penetrometer for penetration resistance of top layers :

 

The pocket penetrometer is specifically used to determine the penetration resistance of top layers (measuring depth 5 mm) and of samples in the field or in the laboratory. When pushing the instrument into the ground, the pin encounters a force of the ground. The spring is compressed by this force. A slip ring is taken along during this operation, which shows on the scale the maximum force that has been encountered. The scale has been calibrated in such a way that The pocket penetrometer is specifically used to determine the penetration resistance of top layers (measuring depth 5 mm) and of samples in the field or in the laboratory.
