Mini SPT&VS Joint Test System

The Mini SPT and VS (Shear Wave Velocity) Combined Test System is used for penetration tests and shear wave velocity tests in laboratory model tests. It can perform combined tests or individual tests separately. 

Penetration system

• Falling height: 50–100 cm

• Hammer weight: 5–20 kg

• Cross-sectional area of the penetration probe: ≤ 10 cm²

• Wave velocity test distance: 10–30 cm

• Number of measuring points: ≥ 3

• The system can be customized to fit the dimensions of the model box.

Technical Specifications
