Digital Automatic Cone Penetrometer

An Automatic Digital Cone Penetrometer is a laboratory device used to determine the Liquid Limit (LL) of fine-grained soils using the cone penetration method. It measures the depth a standard cone penetrates into a soil sample under its own weight within a specified time. Features • Digital penetration display (high precision reading) • Automatic 5-second timing system • Standard stainless steel cone (usually 30°, 80 g or 100 g) • Microprocessor-controlled operation • Stable base with leveling screws • Easy calibration and repeatable results Applications • Determination of Liquid Limit (LL) • Calculation of Plasticity Index (PI) • Soil classification and geotechnical investigations Commonly used in civil engineering and soil mechanics laboratories.
