Product Overview

The WDW Series microcomputer controlled electronic: universal testing machine is mainly used for tensile, compression, bending and other tests on metal and non-metallic materials such as artificial boards, triangular tape, plastic boards, nylon, leather, rubber hoses, etc. Suitable for teaching and research, quality supervision, aerospace,production and manufacturing, construction and building materials units, and other fields

The testing machine complies with GB/ 228 1-2021 “Metallic Materials Tensile Testing  Pat 1: Room Temperature Test Method” and GB/T7314"Metallic Materials Room Temperature Compression Test Methods” and measures performance parameters such as RP Rt ReH, Rel, Rm, E, A, At Agt Z, et. Meet multiple standards and the latest global safety directives, such as ASTM E 4 and SO 75000.5 for mechanical protection.
