Model: WDW-1Y/ WDW-2Y / WDW-5Y (load 100N ~ 5000N)
A single column tensile tester is a sophisticated material testing instrument designed for measuring mechanical properties of various materials under tension, compression, bending, shear, and other loading conditions. As the name suggests, it features a single vertical column supporting a moving crosshead that applies force to test specimens .
These testers are compact (typically tabletop models), cost-effective, and highly versatile, making them ideal for quality control, research labs, and educational institutions where space is limited but precision is essential.
Applications solutions include medical devices, biomaterials, textiles, elastomers, food, small components, wire, paper, plastic, film, fibers and threads, adhesives and many more.
Widely used for industrial application, factory quality control, science and research institute, QC &QA college student training, education institute, testing and inspection center, laboratories, construction company, aerospace, mechanical production, electric appliance fields.
Comply with different standards such as ASTM D638, ASTM D695, ASTM D790, ASTM D412, 624, ASTM D882, ISO 527, ISO 37, ISO 604, ISO 178 and other equivalent BS, ASTM, JIS standard.
