Digital Universal Hardness Tester
HBRVS-187.5 is a high precision, easy operation, high sensitivity metal hardness instrument which is combine the Rockwell, Brinell, and Vickers hardness principle widely used in factory workshops, laboratories, universities and research institutions.
※Large LCD and Microchip control system, makes hardness testing be automatically operated.
※Built-in printer records the main technical data of the entire testing process.
※Adopting manual lifting platform, it completely achieves the realization of the test force imposing, removing, hardness value direct showing and other automated operation.
※High accuracy avoiding the human operational error, is a mechanical and electrical integration also high-tech and advanced hardness tester.
