ZJ-1A strain controlled direct shear apparatus (manual)

Product Information

This instrument is mainly used to determine the shear strength of the graph. Usually four soil samples are used. Apply horizontal force to shear under different vertical pressures (400Kpa, 300Kpa, 200Kpa, 100Kpa, 50Kpa optional) to obtain the shear stress at failure, and then determine the soil's shear strength parameters, internal friction angle, and cohesion based on Coulomb's law.
