Description

The GEOTEST Rock Compression Tester is a high-precision laboratory instrument designed to evaluate the mechanical properties of rock samples under controlled loading conditions. It is widely used in geomechanical studies and underground storage assessments. The system applies uniaxial and triaxial compression to rock specimens, simulating the stress conditions of deep subsurface formations. Equipped with a high-resolution load cell, displacement sensors, and real-time data acquisition, the GEOTEST tester measures compressive strength, elastic modulus, Poisson’s ratio, and failure characteristics. It is particularly useful for underground hydrogen storage studies, where it helps assess rock stability, fracture initiation, and permeability changes under pressurized H₂ exposure. By integrating acoustic transducers, the system can measure acoustic velocity by analyzing P-wave and S-wave propagation through rock samples under stress. These velocities provide key insights into rock stiffness, fracture susceptibility, and mechanical integrity.
