Overview

       The device is mainly used to carry out the rock uniaxial and triaxial compressing experiment and compressive strength experiment,measure rock’s Young’s modulus,Poisson ratio and uniaxial and triaxial compressive strength.The device is equipped with servo oil source to achieve constant torque loading and measure the rock’s microdeformation through high precision extensometer.
