    product description



    Sichuan Shengtuo Testing Technology Co., Ltd. provides geophone acoustic wave tester. The instrument uses ultrasonic vibration excitation, which is mainly used to detect the dynamic Poisson's ratio, dynamic elastic modulus, dynamic stiffness modulus, dynamic shear modulus, dynamic pull modulus, dynamic bulk modulus, and weathering coefficient of rock mass. , cross-hole method and single hole and double-receipt for geological survey, geological crack detection, rock mass state and tunnel surrounding rock loose circle detection. At the same time, the instrument supports the database system CI-DBS.
