HRS-150ND Digital Rockwell Hardness Tester (Convex Nose Type)

This product adopts a special indenter structure (commonly known as the "convex nose" structure). In addition to the tests that can be completed by the general traditional Rockwell hardness tester, it can also test the surfaces that cannot be measured by the traditional Rockwell hardness tester, such as the inner surface of annular and tubular parts, and the inner ring surface (optional short indenter, the minimum inner diameter can be 23mm); it has the characteristics of high test accuracy, wide measurement range, automatic loading and unloading of the main test force, digital display of measurement results and automatic printing or communication with external computers. There are also powerful auxiliary functions, such as: upper and lower limit settings, out-of-tolerance judgment alarm; data statistics, average value, standard deviation, maximum and minimum values; scale conversion, which can convert test results into HB, HV, HLD, HK values and strength Rm; surface correction, automatic correction of cylindrical and spherical measurement results. It is widely used in the detection, scientific research and production of measurement, machinery manufacturing, metallurgy, chemical industry, building materials and other industries.
