TH720/TH720Z Vickers hardness tester is a high-tech and new product combining the optics, mechanic and electrics features. It adopts load cell control system, improves the precision of the test force and the repeatability and stability of the indicating value. It can shows the test force, dwell time, test numbers on the screen, only need to input the diagonal of the indentation when operation, it can automatically get the hardness value and shows on the screen. It can be equipped with CCD image automatic measuring system.
Application Range
Suitable for ferrous metal, non-ferrous metals, IC thin sections, coatings, ply-metals; glass, ceramics, agate, precious stones, thin plastic sections etc.; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.
