The Equotip 3 is a versatile portable metal hardness tester offering extended capabilities and unmatched ease of operation.
This metal hardness tester has a large and clear display which is integrated in the robust ABS plastic housing together with the sealed membrane keypad. With variable background lighting, the LCD display of the metal hardness tester offers a clear overview of the recorded metal hardness values even in dimly lit work areas.
In particularly harsh working environments or for more comfortable handling of the metal hardness tester, the Equotip 3 can be stored in a protective bag.
To date, the Equotip 3 is unmatched in its implementation of the portable metal hardness tester concept and has therefore become established as a globally recognized measuring technique. The Equotip 3 meets the customers needs for a non destructive metal hardness tester.
Equotip uses a proven, dynamic testing principle. An impact body with a hard metal test tip is propelled by spring force against the surface of the test piece. Surface deformation takes place when the impact body hits the test surface, which will result in loss of kinetic energy. This energy loss is detected by a comparison of velocities vi and vr when the impact body is at a precise distance from the surface for both the impact and rebound phase of the test, respectively.
Velocity measurements are achieved through a permanent magnet in the impact body that generates an induction voltage in the coil of the impact device. The signal voltage is proportional to the velocity of the impact body. Signal processing provides the hardness reading for display and storage.
