Model HBRVS-187.5 digital Brinell, Rockwell and Vickers hardness tester with intuitive LCD and single clip control system, makes hardness testing be automately operated. The machine builted-in printer to record the main technical data of the entire testing process. In addition to manual test platform, it completely achieves the realization of the test force imposing, removing, hardness value direct showing and other automated operation. The machine with high accuracy, eliminating the human operational error, is a mechanical and electrical integration also high-tech and advanced hardness testing equipment. Therefore, the test machine has high precision, easy operation, high sensitivity, convenient use, reliable variable-Dutch, showing the stable value, which is widely used in factory workshops, laboratories, universities and research institutions.
