MH310 Portable Leeb hardness tester

MH310 portable Leeb hardness tester, based on Leeb hardness measuring principle, quick and easy on-site test the hardness of series metal materials, support free conversion between Leeb, Brinell, Rockwell hardness scale and others,It uses high-contrast  segment LCD to display clear ,stable performance. integrated high-speed thermal printer ,which can print on-site measurements. It is widely used in annealing, tempering, quenching , quality control for the work piece; hardness testing for machine tool and automobile chassis ; on-site hardness testing of in-service non-removable parts ; quality testing for hardware, forging, machine tools and special steels; quality control for batch production process and so on.Good quality and effective cost ,which is a wise choice for regular need of hardness testing .
