The Rockwell hardness tester is designed according to the Rockwell hardness test principle in the world, can test metal hardness only by contacting a test sample on one side, adsorbs a probe of the Rockwell hardness tester on the surface of steel by virtue of magnetic force without supporting the test sample, and has the test precision meeting the standards GB/T230 and ISO6508 which is not lower than that of a desk-top Rockwell hardness tester. The rockwell hardness test was originally proposed by the american in 1914 by rockwell (s.p.rockwell and h.m.rockwell). Later, they improved the design of the hardness tester twice in 1919 and 1921, and established the prototype of the modern Rockwell hardness tester. Wilson (C.H Wilson) performed a more recent design in 1930 to improve the Rockwell hardness test method and apparatus. China has produced Rockwell hardometers for touch screen control, numerical display, and curve display and automatic printing of test data. The Rockwell hardness detection method has the characteristics of simple operation, quick measurement and direct reading from a dial indicator or an optical projection screen or a display screen. As with the brinell and vickers hardness tests, are among the three most commonly used hardness tests.
