GWA-1000B electro-hydraulic servo strand testing machine dedicated to test the mechanical properties of steel strand, electro-hydraulic servo strand testing machine equipped with Lenovo computers, HP printers, large gauge electronic extensometers, optical encoder and full-featured universal testing software, you can easily complete test function; comes with a strand-specific extended jaws ensure intermediate specimen breaks. Thereby further improving the success rate of the test. The test results can query and print (force - displacement, force - deformation, stress - displacement, stress - deformation, force - time distortion - time) six kinds of curves and related test data with the software self-test function, can self-diagnose faults, Sees the software. Strand tensile strength can be determined, the mechanical properties of non-proportional extension strength, elastic modulus, elongation and the like.
