This spring-type penetrometer can be used in the field to control soil compaction. The stem is calibrated to 150 lbf x 2 lbf divisions, and a sliding collar indicates the applied load. A rapid estimate of the moisture content of soil can be obtained by comparing the amount of penetration of the needle for a corresponding load, with a laboratory determined moisture/density curve for a similar soil.

In this method of determining the dry density of in-situ soil, a core-cutter of known volume is driven into the soil by a rammer. The core-cutter is removed, trimmed and the soil obtained is weighed and dried for a moisture/density check.
