Inner Rods for Mechanical CPT

All Gouda-Geo CPT sounding tubes are suitable for mechanical cone penetration testing (in short CPTm or mCPT). The key characteristic of mechanical CPT is the fact that the reaction forces encountered by the mechanical cone are transferred to the measuring head by means of so-called inner rods.

These rods can move freely without any obstruction inside the CPT sounding tubes. The rods are manufactured out of specially selected tool steel. The rods have an outer diameter 15 mm.
