WDW High Force Double Comlumn Computer Control Electronic Universal Testing Machine
Introduction

This electronic universal testing machine consist of host machine, mechanical limit switch, electrical system, test accessaries, etc . It is suitable for tensile, compression, bending and other mechanical property for metal and non-metal material, such as steel, aluminum,copper,geotextile,plastic,rubber,thread,wood,alloy,PVC,spring,electrical wire and cable, composite material, profiled bar, waterproof roll and all ASTM, ISO, JIS, DIN, BS, EN relative material mechanical testing standards. The machine is calibrated according to international norms requirement as ASTM E4, ASTM E83, ISO7500-1, ISO9513 and supply a full detailed calibration certificate. They are essential testing instruments for quality control section, university and college, research institution and mining enterprise quality lab.
