1.INTRODUCTION:
HBRVU- 187.5 Brinell Rockwell & Vickers Optical Hardness Tester use rotating test force transform construction and optical measuring system. There is a measuring device which can measure the indentation in it. This machine has a variety of test force and a variety of indenter for measuring metal and the Brinell/Rockwell/Vickers hardness of the test- piece. It is a multi- purpose hardness tester which can use different test methods to measure the hardness.
This hardness tester is widely used to measure ferrous metal, nonferrous metal and alloy and carburized layer and chemical treatment layer. It is widely used in factory workshops, laboratories, universities and research institutions.
