Proceq Equostat 550 Portable Rockwell Hardness Tester

Hardness Measurements Made Easy

The Proceq Equotip 550 Portable Rockwell test principle follows the traditional Rockwell static test method which is particularly suited for scratch-sensitive, polished or thin parts as well as for profiles and pipes.

In combination with the Proceq Equotip Leeb Impact Devices, the Proceq Equotip 550 can be extended with the Leeb hardness principle following the dynamic (rebound) method. This additionally allows automatic on-site correlation of Leeb to Portable Rockwell true indention hardness value.

Stationary hardness testers can only accomodate test pieces of limited size. The portability of the Proceq Equotip 550 Portable Rockwell works well in outdoor, factory and lab environments.

The Proceq Equotip 550 Portable Rockwell probe can connect directly to a PC or laptop for live user guidance and hardness test displays.

Compared to stationary hardness testers the Proceq Equotip 550 Portable Rockwell uses a sharper indenter and smaller loads. The test measurement is standardised to DIN 50157 (metals) and ASTM B724 (Aluminium). The conversions to Rockwell hardness to many other scales follow the ISO 18265 and the ASTM E140 tables, respectively. Can be used on materials such as Inconel and Duplex Stainless Steel
