The Load Ring Penetrometer is a cone-type penetrometer designed for rapid, reliable determination of the bearing strength and compaction degree of subgrades and soils in the field. Widely used by geotechnical engineers, highways contractors, and site investigation teams, it provides an immediate indication of penetration resistance without the need for laboratory testing.
Readings can be directly correlated to standard or modified Proctor compaction data, making it an essential tool for quality control during earthworks, road construction, and ground improvement projects.
