Brinell Hardness Tester is a lab instrument to measure the hardness value of all kinds of metals according to Brinell hardness principle ASTM E10 and ISO 6506. They are widely used in metallurgy, forging, casting, hardness steel and nonferrous metals industries, as well as in the laboratories, universities, college and scientific research institutes.- Test force loading and unload motorized without heavy weight-5.6 inch touch screen operation interface- Adopts electronic auto loading Use 0.5% accuracy load sensor to feedback- Microchip control system, automatically compensate the test force lost during testing- Test force and load dwell time can be set on the touch-keyboard, reliable repetition, precise reading, and easy operation.HBS-3000 is a digital control and reading Brinell hardness tester. ally. the indentation impression can be directly measured on the instrument through microscope, and LCD screen indicates the diameter, the hardness value and 17 different hardness Scales for example HR, HV tables as well as the HBW range under the present presetting.
