Main Features:
Digital Brinell Rockwell & Vickers hardness tester is equipped with a newly-designed large displaying screen with good reliability, excellent operation and easy watching, thus it is a high-tech product combining the optic, mechanic and electric features. It has Brinell, Rockwell and Vickers three test modes and 7 level of test forces, which can test several kinds of hardness. Test force loading, dwell, unload adopts automatic shifting for easy and fast operation. It can show and set the present scale, test force, test indenter, dwell time and hardness conversion; the main function is as follows: Selection of Brinell, Rockwell and Vickers three test modes; Conversion scales of different kinds of hardness; Test results can be saved for checking or be printed out, automatic calculation of maximum, minimum and average value.
