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”).
The Equostat 3 works well in outdoor, factory and lab environments. It has only very few requirements on test piece geometries.
- Accurate, rapid and reproducible metal hardness readings;
- Measurements are independent of the material and sample dimensions;
- Testing range from very soft (aluminum) up to very hard materials (case-hardened steel);
- Measurement in HRC, integrated conversions to HV, HB, HRA, HRB, HR15N, Rm possible;
- Small test load yields small penetrations of only a few μm;
- The Equostat 3 probe can be used in either a clamp or freehand;
- In addition to the Equostat 3 probe, all the impact devices of the Equotip metal hardness tester can be used to also conduct rebound hardness testing with the same indicating device.
Applications:
- Precise metal hardness testing of very soft materials through to very hard materials;
- Thin parts, profiles and pipes of a wall thickness ≤ 2 mm, sheets, coiled metal, as well as parts as thin as 0.2 mm (0.008”), depending on the hardness level;
- Testing on scratch-sensitive or polished surfaces;
- Metal hardness testing of heat-affected zones near welding seams.
