Consolidation & Direct Shear System for Saturated & Unsaturated Soils HC-UST

System Description

This system performs tests on both saturated and unsaturated soils under fully automatic control. It is equipped with an automatic compensation device for drainage and evaporation. Air pressure is applied via an electrically controlled proportional valve with continuous regulation from 0 to 1 MPa. It is an indispensable testing instrument for geotechnical engineering and mechanics laboratories, and is widely used in civil engineering, hydraulic engineering, and related fields.

System Features

• Axial load is automatically controlled by motor to ensure stability during shearing.

• Axial and shearing motions are controlled independently, allowing customized control for any shear box test.

• High-precision electronic weighing module is adopted with an accuracy of 0.001g.

• Proportional valve enables smooth air pressure loading and unloading.
