Applications:

WAW-D Series Computer Control Servo Hydraulic Universal Testing machine are guaranteed to meet ISO15579-2000, ISO679, ISO7438-1985, ISO6892, EN100021-1-2001, ASTM E8M, JIS Z2241-1998, ISO75000-1, ISO4012, ISO10065 and other international and national specifications, which are suitable for tension, compression, bending, shear and other tests by adding different test fixture for metal and non-metal materials. It adopts hydraulic power pack to drive the piston in the oil cylinder to provide testing load. By using load cell and photoelectric encoder, the computer is timely showing the testing parameters like testing load, piston stroke, deformation of specimen and various kinds of testing curves etc. This machine is servo control mode and the computer with strong function software does data processing and issues the test reports. The software based on Windows system is able to make automatic calculating of test results, i.e. tensile strength; upper / lower yield strength, Non proportional stress point etc. Report creation function makes it is very simple to make testing report in needed format. It is necessary inspect device in the filed of steel and iron factory, the laboratories of scientific research institutes, infrastructure construction organs, machinery plants and education for research and teaching, etc.
