Proctor Penetrometer

Proctor Penetrometer

STANDARD: ASTM D1558

The Proctor Penetrometer is a soil testing instrument designed for evaluating the penetration resistance of soil and assessing soil consistency and compaction conditions. It is commonly used in geotechnical and construction applications where rapid field evaluation of soil conditions is required.

The instrument provides a practical method for assessing soil resistance by measuring the force required to penetrate the soil with a specified probe. It is suitable for soil testing laboratories, construction sites, geotechnical investigations and field quality-control applications.
