Features & Applications:
The new pocket penetrometer by Geotest, 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. Strength in tons per sq. ft. or kg per sq. cm. to a maximum of 4.5 is obtained by noting the position of an indicating ring on the scale. This reading is retained until manually reset.
The penetrometer is made from hard anodized aluminum, a material tougher than steel. The scale is virtually indestructible and is guaranteed for 1 year. An allen wrench, used to loosen the stainless steel pin for cleaning, and a carrying case with belt loop are included with the pocket penetrometer. The allen wrench is also used to tighten the optional 1" diameter adapter foot. Abbreviated instructions are printed on carrying case. Dimensions are 6.25 x 0.875" (158 x 21mm) length and diameter. Net weight: 0.25 lb (115g).
