Hardness Testing

Equotip 550 Portable Rockwell

No thickness limitation of tested objects - perfect for thin metal sheets

Faster than stationary Rockwell hardness testers, yet very accurate

Purely material-independent method thanks to the direct measurement of the indentation depth

Applications:

Hardness testing of thin metal sheets and wires / Hardness testing of casts, flanges, shafts, and bars/pipes / Quality and wear control of turbine blades and brake systems

...or add to quote-cart

Extremely precise, and material independent version of conventional Rockwell method

Resolution & depth

The only portable measurement method that has practically no minimal thickness limitation - perfect for thin sheets of metals, any material.

Versatility

Equally reliable, accurate and standardized but faster than stationary Rockwell hardness testers.

User Experience

Material independent method - that can be combined with Leeb and UCI in one measurement device. One device - all applications.

FAQ

How deep can I measure with the Pundit PD8000?

No. Portable Rockwell method can be applied for any metal object regardless of its mass.

What materials can be investigated with portable Rockwell and what materials require corrections?

Portable Rockwell can be used to investigate any type of metal objects. Portable Rockwell is based on direct measurement of penetration depth and therefore does not require any material correction. Portable Rockwell is...

What is the principle behind the portable rockwell method?

The Portable Rockwell metal hardness tester is based, as its name suggests, on the static Rockwell measuring principle where the penetration depths under a defined preload are measured before and after application of a...

What is the minimum thickness of the thin metal sheet that can be successfully tested with portable Rockwell?

Test objects should have at least 10 times the thickness of the penetration depth to avoid influences on the measurement value. The penetration depth and so the minimum thickness can be assessed from the attached plot when...
