Multi-Functional Penetrometer System

Standard Penetration Test (SPT)

• The Standard Penetration Test (SPT) is one of the most widely used in-situ testing methods in geotechnical engineering. The test evaluates soil density, strength, and engineering properties based on the blow count (N-value). It provides critical data for foundation design, soil classification, and bearing capacity analysis.

• The system is designed in accordance with ASTM D1586, ISO 22476-3, and other relevant international standards, ensuring high accuracy, repeatability, and ease of use in field applications.

Dynamic Probe Light (DPL)

• The Dynamic Probe Light (DPL) is a light dynamic penetration testing method used to evaluate the density and consistency of shallow soils. The test determines soil resistance by recording the number of blows required for a specified penetration depth.

• The system utilizes a 10 kg hammer with a 500 mm free fall height and complies with ISO 22476-2 and DIN EN ISO 22476-2, ensuring reliable and repeatable field measurements.

Dynamic Probe Medium (DPM)

• The Dynamic Probe Medium (DPM) is designed for investigating medium-dense soils and determining soil penetration resistance for geotechnical site investigations and foundation assessments.

• The system utilizes a 30 kg hammer with a 500 mm free fall height and complies with ISO 22476-2, providing accurate and consistent penetration measurements.

Dynamic Probe Heavy (DPH)

• The Dynamic Probe Heavy (DPH) is used for testing dense granular soils and stiff cohesive soils, providing reliable information on soil density, bearing capacity, and subsurface stratification.

• The system utilizes a 50 kg hammer with a 500 mm free fall height and complies with ISO 22476-2 and DIN EN ISO 22476-2, ensuring high accuracy under field conditions.

Dynamic Probe Super Heavy (DPSH)

• The Dynamic Probe Super Heavy (DPSH) is a high-energy dynamic penetration testing method used for deep geotechnical investigations and bearing capacity evaluations. The test results show strong correlation with the Standard Penetration Test (SPT).

• The system utilizes a 63.5 kg hammer with a 750 mm free fall height and complies with ISO 22476-2, providing accurate and dependable performance for demanding field applications.
