Metal Hardness – Equostat

The Equostat features excellent sensitivity through small penetration of a few µm and is therefore particularly suited for the testing of metal hardness on scratch-sensitive and polished parts or on thin parts, profiles and pipes with a wall thickness that is below 2 mm. The Equostat was developed for accurate, rapid and reproducible metal hardness from only one side.

The Equostat is a complement to Proceq’s portable rebound metal hardness testers as it resolves most limitations associated with the dynamic testing method.

Features

  • Accurate, rapid and reproducible metal hardness results from measurement of penetration depth
  • Measurements are independent of the material and of the body dimensions
  • Testing range from very soft (aluminum) up to very hard materials (case-hardened)
  • Integrated conversions (HV, HB, HRC, HRB, HR15N, Rm)
  • Transfer of up to 5’000 stored readings to a PC via RS232 using Equolink 2
  • Excellent sensitivity down to small penetrations of only a few μm
  • The probe can be used in either a clamp, bench press or freehand
  • In addition to the R5 probe, all the impact devices of the metal hardness tester Equotip 2 and Equotip 3 can be utilized to conduct rebound hardness testing with the same indicating device

Applications

  • Quality 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, and pieces as thin as 0.2 mm (0.008”) depending on the hardness level
  • Scratch-sensitive and polished surfaces
  • Metal hardness of heat-affected zones near welding seams

Proceq offers accessories such as a hand activated clamp , a free-hand flat foot for metal hardness testing on large surfaces, support adapters for round parts, and a test stand.

Warranties

  • Standard 2-year limited warranty on electronic parts

  • Optional extended warranty periods up to 3 additional years

Standardization

  • DIN 50157
  • DGZfP Guideline “Mobile Härteprüfung“
  • VDI/VDE Guideline 2616 Paper 1
