1. Features:
1) Adopting fully digital broadband electro-hydraulic servo valve to drive precise hydraulic cylinder, with three closed-loop automatic control of test force, displacement, deformation, it is mainly used to make tensile, compression, bending tests, etc. It satisfies standards GB/T16826-2008 and GB/T228-2008 as well as ISO, ASTM, JIS, etc.
2) Using independent hydraulic servo loading system and high precision broadband electro-hydraulic servo valve to ensures system high precision ,efficiency and rapid response; With independent hydraulic clamping system to ensure that specimen can be fixed tightly and without slipping;
