Model：Quasi Static Testing System
Country of Origin：USA
Use：Computer controlled servo-hydraulic multi-actuator testing systems allow for fatigue testing, quasi static testing including Pseudo-Dynamic Testing (PST).
Use: GDS Unsaturated Triaxial Testing System (UNSAT) is an extension to traditional triaxial testing, in that soils from above the water table may be tested under conditions approaching the in-situ stress state and degree of saturation or partial saturation.
Country of Origin：UK
Use：The GDS Triaxial Testing System (GDSTTS) is a fully automated triaxial testing system designed principally for stress path testing. The GDSTTS is based on the classic Bishop & Wesley type stress path triaxial cell which controls stress directly on the sample. The system can be configured using Enterprise, Standard or Advanced level controllers. The 38/50mm cell is for up to 7kN axial force, with the larger 70/100mm cell up to 25kN. This is the system of choice for teaching laboratories and researchers.
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
