The Webster hardness tester utilizes the Webster hardness measurement principle and is specifically designed for measuring the hardness of aluminum alloy, brass, copper, soft steel, and various other metal materials. This instrument is particularly well-suited for production facilities, sales operations, and construction sites where rapid, non-destructive, piece-by-piece qualification inspection of metal profiles, plates, tubes, and similar materials is required.
Employing advanced eddy current induction measurement technology, the instrument delivers exceptional repeatability and measurement accuracy. It features multiple built-in hardness systems with automatic conversion capabilities between Webster (HWA), Rockwell (Rockwell Hardness E), Rockwell (HRF), Rockwell (HRB), Vickers (HV), and Brinell (HB) scales.
