Product Description

Wdw-300kn Universal Material Tensile Testing Machine with High-Precision Load Sensor

1 Overview
This universal testing machines is equipped with computer, printer, general test software, and various fixtures, which is designed for measuring strength in tension, compression, bend, flexture, tear, peel, shear, and adhesion test. It is widely used for metal, geotextile, hard plastic, timber, rubber, concrete and many other materials. Test results can print (force - displacement, force - deformation, stress - displacement, stress - deformation, force - time distortion - time) in six kinds of curves with related test data. The software self-test function enables problems self-diagnosing. It is an ideal testing equipment for the industrial and mining enterprises, scientific research units, universities and colleges.
