Ensemble de pénétromètres Proctor

The durable metal body, calibrated spring mechanism, precision gauge, and interchangeable stainless-steel tip set provide high repeatability across various soil types. Penetration resistance (kg/cm² or lbf/in²) is read directly from the dial by applying the piston to the soil surface; these values are correlated with the Proctor compaction curves to obtain immediate information regarding optimum moisture and compaction conditions. The system offers a measurement range of 10–150 lbf and can be used with different tips in clay, silt, and sandy soils. The ergonomic design enables easy single-operator use, while the portable case allows rapid assessment in the field. The scale is designed to display penetration resistance with high precision.
