Pocket Penetrometer - Soil Tester

Description

Easy to use with easy-to-read results. Penetrometer is easy to use: push the indicating ring to the highest point touching the body and insert the piston until the calibration mark is level with the soil. The easy-to-read scale indicates strength from 0 to 4.5 tons per sq ft. The reading is maintained until manually reset.
Penetrometer is constructed from anodized aluminum and measures 6-1/4"L x 7/8" dia. Use an Allen wrench to loosen the stainless steel pin for cleaning

The new pocket penetrometer, weighing less than 5 ounces, reduces the human error in classification of cohesive soils.
The penetrometer can also be used with the torsional vane shear tester (TVST) for rapid estimation of the degree of internal friction of soil.
The pocket penetrometer is now required by OSHA on most excavation jobs and its use is mandated in the OSHA manual titled “Construction Standards for Excavation”.
It is a spring operated device used to measure compressive strength by pushing a 0.25" (6.4mm) diameter loading piston into the material being measured up to a calibration groove machined on the piston 0.25 from the end., “easy to chew” chunks
