Metal Hardness Tester – Equostat 3

The Equostat 3 was developed for accurate, rapid and reproducible metal hardness testing. It features excellent sensitivity through small penetration of a few µm and is therefore particularly suited for testing metal hardness of surface layers on scratch-sensitive and polished parts or on thin parts, profiles and pipes with a wall thickness that is below 2 mm (0.08”).
