This Automatic Direct Shear Test Machine, used for determination of the consolidated drained shear strength of a coarse aggregate soil material in direct shear. The difference between digital and automatic direct shear test machines is in Automatic machine Azmoon use a 1000W servomotor to reach normal stress in range of 0.25-5 kg/cm2 with high accuracy.
