EQUOTIP 3 Portable Hardness Tester

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 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 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.


  • 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)
  • Down-/upload data from/to PC via USB, Ethernet or RS-232


  • Good for most metals
  • Excellent for material selection, acceptance and production level testing
  • The metal hardness tester Equotip 3 is ideal for on-site testing of heavy and large components before and after installation
  • Handy for difficult to access or confined metal hardness test locations
  • The Equotip 3 metal hardness tester is accurate also on curved test surfaces (R > 10 mm)


The following standards can be applied to the metal hardness tester Equotip 3: 

  • ASTM A956
  • DIN 50156
  • DGZfP Guideline "Mobile Härteprüfung"
  • VDI / VDE Guideline 2616 Paper 1
