H-4200M - Humboldt Pocket Penetrometer Metric (Tire Gauge Design)

Used by field personnel to check the visual classification of soils. Useful to make quick estimates of unconfined compressive strength of cohesive soils, especially in field applications. 
 
The metric version (H-4200M) reads in tonnes per square meter, will in increments of 10 with a max of 45 tonnes per square meter. It shows numbers for the following: 0, 10, 20, 30, 40. Whit tick marks in between the numbers.

  • Description
    H-4200M - Humboldt Pocket Penetrometer Metric (Tire Gauge Design) - Soil Testing 
      

    Applications for this product

    • The pocket penetrometer can quickly verify whether excavation sidewalls require shoring, based on OSHA cohesive soils classifications.

    • The penetrometer indicates consistency, shear strength, and approximate unconfined shear strength. It has a direct-reading scale in tons/sq m, or kg/sq cm, which corresponds to equivalent unconfined compressive strength. It features high-quality construction.

    • While the pocket penetrometer is a great tool for fast evaluations of soil in the field, it should not be used to replace laboratory testing or field analysis or be used to produce foundation design data.

    Features of this product

    • The pocket penetrometer's penetration piston is pushed into the soil surface to a calibration groove machined into the piston at 0.25" (6.4mm) from the end. The resistance of a calibrated internal spring registers the penetration force on an engraved scale.

    • The Humboldt pocket penetrometer provides a direct-reading scale in tons/ft2, or kg/m2, which corresponds to equivalent unconfined compressive strengths. It has a range of 0 to 4.5 tons/m2. The penetrometer features high-quality construction with an anodized aluminium body and a stainless steel plunger. It also includes a belt-loop style carrying case and operating instructions.

    • The unit comes with a belt loop case/sleeve that can be worn on technicians belt and operating instructions.
