Superficial Rockwell Tester

Superficial Rockwell Hardness Testing is used to measure the hardness of the material of the surface of a metal. It is commonly used for the hardness testing of thin parts or parts with hardened exterior such as case hardened steel. The scales this tester uses are 15T, 30T, 45T, 15N, 30N, and 45N. The lower limit for material thickness is 0.005″ for the 15T scale and increases to 0.015″ for the 45T range of measurement.
