The universal testing machine (tensile tester) underpins accurate detection with its precise parameters. It features a standard force range of 0-500kN, a force accuracy of Grade ±0.5, a displacement resolution of 0.001mm, and a stepless adjustable test speed from 0.01 to 500mm/min, supporting multiple test modes such as constant force, constant speed and cyclic loading. Widely applied in tensile, compression and bending tests of metals, plastics, rubbers and other materials, it provides efficient and accurate mechanical property data support for manufacturing enterprises and testing institutions, boosting the upgrade of product quality control.
