Proceq Equostat
Portable Hardness Tester

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 depending on the hardness level

• Scratch-sensitive and polished surfaces

• Hardness of heat-affected zones near welding seams

Accurate, rapid, and reproduceable results from measurement of penetration depth under defined forces and therefore

• independence of material (no choice of material curves necessary)

• independence of body dimensions and geometry

• measures from one side - no backing necessary

Excellent sensitivity through small penetration of a few µm and therefore particularly suitable for

• scratch-sensitive and polished surfaces

• thin parts, profiles and pipes with a wall thickness = 2 mm

• hardness profile in heat-affected zone of 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.
