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

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 lightning, the LCD display of the Digital Portable Static Hardness Tester (Equotip-3) 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 the metal hardness tester Equotip 3 can be stored in a protective bag. To date, 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.
Features :
- Equotip 3 is a hand-held metal hardness tester with a rugged shock-resistant housing and sealed membrane keypad
- The metal hardness tester Equotip 3 converts directly to all common hardness scales (HV, HB, HRC, HRB, HRA, HS, Rm); creates and uses another up to 20 customer-specific conversions for uncommon alloys
- Highly accurate ± 4 HL (0.5% at 800 HL) with automatic correction for impact direction
- The Equotip 3 metal hardness tester offers a wide measurement range
- Internal storage of ~100’000 measured values in a flexible user-defined file/folder structure
- The metal hardness tester Equotip 3 offers user profiles for a quick change of test setup (with password protection)
- Download upload data from / to PC via USB, Ethernet or RS - 232
- Proceq offers a unique variation of impact devices and support rings to serve most metal hardness test requirements
