The Pocket Penetrometer provides accurate measurements of the compressive soil strength. This 6-1/4" unit is spring-operated, and it measures strength in tons/sq. ft. (kg/sq. cm) by pushing a 1/4" diameter piston into the soil to a depth of 0.25". The end area is a 0.25" compressive load, which is indicated by reading a scale on the piston barrel. A friction ring indicates maximum reading. Made of anodized aluminum. An Allen wrench and plastic carrying case with a belt loop are included. A special 1" diameter adapter foot is available as an option for use in very sensitive soils.
