Model: Sonic Viewer 2i
Country of Origin: Japan
Use: Sonic Viewer 2i uses ultrasonic waves to measure the propagation times of boring cores and rock specimens with high accuracy to determine the P-wave and S-wave velocities and to calculate the mechanical constants (dynamic Poisson’s ratio, dynamic elastic modulus, and dynamic shear modulus).
Country of Origin：United Kingdom
Use：A highly sophisticated, research focused, version of the traditional Hoek cell that can be fully instrumented. With 70MPa cell pressure and maximum loads up to 2MN.
Country of Origin：UK
Use：The HPTAS is a high load, high pressure load frame-based triaxial testing system for accurate testing of rock samples. GDS have been making high pressure automated triaxial testing systems for rock mechanics for over 20 years, with systems installed at leading research and commercial institutes around the world.
The high density resistivity instrument High density electrical apparatus is a traditional method based on the theory of a new generation of electrical equipment in the development of computer and information monitoring based on modern scie
