The KASON W-20S Webster Hardness Tester is based on the Webster hardness testing principle, ideal for measuring the hardness of aluminum alloys, brass, copper, mild steel, and other metal materials. It's especially suited for quick, non-destructive, and individual piece qualification testing of metal profiles, sheets, and tubes in production lines, sales environments, and on construction sites.

Utilizing eddy current induction technology, this tester ensures excellent repeatability and measurement precision. It supports multiple hardness measurement systems including Webster (HWA), Rockwell (HRE, HRF, HRB), Vickers (HV), and Brinell (HB), with easy on-device conversion.
