Introduction
WAW-C Series Computerized Electro-hydraulic Servo Universal Testing Machine is newly designed for tensile, compression and bending test of metal materials, steel rebar and non-metal materials. It has lots of patents and good structure （Disc motor drive crossbeam lift,Japan technology）.It adopts two column and two screws structure, high stiffness. It uses high accuracy load cell to measure testing force, encoder to measure displacement of work bench, electric extensometer to measure extension. Close loop control software can auto get test tensile strength Rm, yield strength ReH/ ReL, max. testing force Fm, non-proportional extension Rp0.2, elongation rate A%, extension at max. testing force Agt, modulus of elasticity E, etc testing results. In testing standard, it conforms to international standards. The software based on Windows system is able to make automatic calculating of test result, i.e. tensile strength, up/low yield strength, Non proportional stress point etc.. Report creation function makes it very simple to make testing report in needed format. This machine is widely used in different areas and facilities.
