SACP – Soil Assessment Cone Penetrometer A2451 Mexe-Cone

The Soil Assessment Cone Penetrometer (SACP or MEXE-CONE) is a lightweight instrument for rapidly measuring indepth resistance to penetration, indicating with a dial, in terms of California Bearing Ratio (CBR). Developed in conjunction with the UK Ministry of Defence, the SACP is a robust and reliable instrument used throughout the world by both commercial and military establishments.


  • Measurement range for CBR is from 0-15% CBR
  • Soil trafficability measurements can be made using the Cone Index (CI) range
  • The linear CI range is from 0-300 and has 60 divisions, each of 11.12 N (1.13 kgf). Full deflection is 667 N (67.9 kgf)
  • Steady penetration of the cone into the soil is required and readings are taken from the dial at 75 mm (3”) intervals during penetration to a maximum depth of 600 mm (24”)
  • In fine-grained soils, for which the SACP is primarily intended, measurements correlate closely with CBR values, measured in-situ with conventional equipment
  • The SACP is supplied complete with carrying case, which contains one CBR cone, one CI cone, one top rod, three extension rods (150mm each), tools and operating instructions
  • Weight (including case) 2.5Kgs
