MH320 portable Leeb hardness tester is based on Leeb hardness measurement principle, it can be quickly and easily used for on-site testing hardness of metallic materials and support free conversion between Leeb, Brinell, Rockwell hardness and other scales. 

It uses 128 × 64 dot matrix LCD screen, rich information, intuitive, stable performance and integrated high-speed thermal printer, which enables printing with instant measurement results.It can be widely used in metal processing and manufacturing, special equipment, permanent component failure analysis, inspection and other fields. It is particularly suitable for large parts and non-removable part of the on-site hardness testing. It is to improve production efficiency and pass rate and is a wise choice to save the cost of production.
