| Alert for mines, they tested the runway with a soil penetrometer, a long rod with a cone-shaped end and a sliding weight. |
| The Compaction Detector is a soil penetrometer cone and shaft pushed by a hydraulic cylinder, rather than by hand, into the ground. |
| There was a significant correlation between the cone penetrometer readings and the nuclear density measurements. |
| An aluminum stepwedge penetrometer was exposed simultaneously with each radiograph for use as a standard of reference. |
| Fruit firmness, as determined by penetrometer, measures the force required to press a blunt-ended probe into the tissue. |
| The penetrometer value measures the energy required to bury a ball in sand. |
