This Webster Hardness Tester is a portable instrument for measuring the hardness of aluminum alloys, brass, copper, and soft steel. It adopts the eddy current induction principle to determine hardness. The Webster scale (HWA) is one of the hardness scales the instrument can measure, along with Rockwell (HRE, HRF, HRB), Vickers (HV), and Brinell (HB).
