1. Purpose and overview

 It is mainly used in the compression and shear properties of unsaturated soil, and is suitable for soil mechanics test research in colleges and universities. The instrument uses a stepper motor as the driving source, the shear rate of the direct shearing instrument is infinitely variable, and has the functions of fast retreat and fast forward; set the limit device; the instrument is equipped with a load sensor, a displacement sensor, and a pore pressure sensor; digital display Intake value; air pressure control adopts precision pressure regulating valve, and the control is stable and reliable.
