Back to the Penetrologger Family

A mechanical, scientific instrument for the determination of the penetration resistance of the ground.
A graph is drawn on weather-proof plasticised paper which can be re-used to show trends with continuous measurement up to 80cm. Ideal for measuring disturbed layers and the effect of compaction on different soils.

  • Self-recording of continuous measurements plotted on a chart
  • Clearly shows disturbed layers
  • Will prove compaction situation
  • Weather proof charts
  • One-push measurement
  • Ideal for contractors and agronomists
  • Weather-proof body

Penetrograph Applications

  • Geotechnical soil research
  • Trafficability or load bearing capacity research
