Static Cone Penetrometer

Static Cone Penetrometer


The Static Cone Penetrometer is used to evaluate the consistency of soils, their level of compaction and the bearing capacity of shallow foundations and pavement subgrades. Specifically developed for use in fine grained soils, particularly soft soils, they use a 60° cone with an area of 1.5 cm². An optional cone with a 3 cm² area is available for use in very soft soils.

  • Dual rod construction isolates cone resistance from shaft friction
  • Pressure gauge ranging from 0 to 70 kg/cm² reads cone resistance directly, eliminating need for proving ring conversions
  • Stainless steel and anodized aluminum construction for reliable performance

Standard models include:

  • A 60° cone with a maximum area of 1.5 cm²
  • A Starter Rod Assembly designed to withstand an axial force of 250 lbf (340 N•m) maximum
  • Pressure gauge marked in kg/cm²
  • Operating Instructions and parts list
