Product Description
LFTD1804 stress path triaxial apparatus is an advanced laboratory geotechnical testing instrument, which is mainly used for accurate and automatic testing of shear strength, deformation characteristics and stress-strain relationship of various soils in the laboratory. It can complete back pressure saturation, isotropic consolidation, anisotropic consolidation, K0 consolidation, standard triaxial shear (UU/CU/CD), and stress path triaxial tests.
The vertical loading of the system adopts multi-functional loading frame with loading range of 30kN~100kN. It has LCD touch screen, which supports manual operation and full-automatic operation from PC. Cell pressure and back pressure control adopts advanced automatic pressure / volume controller with range of 2MPa~3Mpa, which also have LCD touch screens. Triaxial cell available for sample diameter is 38mm~150mm.
