4. Features of testing machine

l        Adopting aluminum alloy cover, with attractive streamline structure

l        Mainly used to test mechanical properties for metal, non-metal and composite materials

l        Adopting precision auto control and data acquisition system to realize fully digital adjustment to data acquisition and control process. During test, it can test max. Bearing tensile force, compression force, tensile strength, deformation, elongation, yield point and other technical specifications

l        After test, the above parameters can be calculated automatically through main controller according to the test parameters, which are set before test and meantime display the corresponding test results. All test parameters can be saved and inquired after test, also can be printed out.

l        With remote control box to realize speed adjustment of crossbeam, flexibly and freely switched

l        With functions of automatic return to original position, intelligently, efficiently, quickly

l        With limit position function of any working position and over voltage, over current protection functions, reliable and safe

l        With many control modes of constant speed control to force, stress, deformation, strain and low cycle and user self-programming control

l        Switch among many test curves: stress-strain curve, load-deformation curve, load-displacement curve, load-time curve, deformation-time curve, displacement-time curve. Partial enlargement, overlap and comparison.
