Universal Hardness Testing Instrument (HBRVS-187.5)

This hardness tester serves the purpose of measuring the hardness of Rockwell, Brinell and Vickers for ferrous, non-ferrous metals, hard metal, alloy, carburized layers and chemical treating layers.
Features

With intuitive 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 test platform, it completely achieves the realization of the test force imposing, removing, hardness value direct showing and other automated operation.

With high accuracy, avoiding the human operational error, is a mechanical and electrical integration also high-tech and advanced hardness tester.

It has high precision, easy operation, high sensitivity, reliable variable-Dutch, showing the stable value, which is widely used in factory workshops, laboratories, universities and research institutions.
Introduction of Digital Brinell, Rockwell & Vicker Universal Hardness Tester

Model HBRVS-187.5 digital Brinell, rockwell and vickers hardness tester with intuitive LCD and singleclip 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 compeletly achieve the realization of the test force imposing, removing, hardness value direct showing and other automated operation.
