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. The Equostat 3 probe can be connected directly to a laptop or a PC. Alternatively, the probe plugs into the Equotip 3 indicating device to combine the Rockwell principle of Equostat with the Leeb rebound principle of Equotip 3 to become the most versatile hardness tester. Live user guidance dialogs enable the user to obtain very accurate and highly reproducible measurements.
Features:
- Accurate, rapid and reproducible metal hardness readings
- Measurements are independent of the material and sample dimensionsTesting 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
- Transfer of up to ~100’000 stored readings from the Equotip 3 indicating device to a PC using Equolink 3
- 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
Application:
- 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
Proceq offers accessories such as a measuring clamp or several support feet adapt to freehand hardness measurements on various test piece geometries
