EQUOSTAT

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

While rebound hardness testers are not suitable to measure very light parts of certain geometries, the portable Equostat is well-suited for testing light, thin-walled or tubular parts.

The Equostat measures according to the Rockwell principle where the penetration depths under a defined preload are measured before and after application of a larger force.

These low-load penetration depth measurements are accurate, rapid and reproducible.

The difference between the before and after penetration depths reflects the plastic deformation and, therefore, the hardness.

Features

Accurate, rapid and reproducible 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 Equotip 2 and Equotip 3 can be utilized to conduct rebound hardness testing with the same indicating device

Applications

Quality testing of very soft materials through to very hard materials
Thin parts, profiles and pipes of a wall thickness ≤ 2 mm, sheets, coiled metals, and pieces as thin as 0.2 mm (0.008”) depending on the hardness level
Scratch-sensitive and polished surfaces
Hardness of heat-affected zones near welding seams

Proceq offers accessories such as a hand activated clamp (incl. in the “clamp unit”), a free-hand flat foot (incl. in the “R-H unit”) for testing on large surfaces, support adapters for round parts, and a bench press to address individual testing requirements.
