• Equotip 550 Portable Rockwell

Equotip 550 Portable Rockwell


The Equotip 550 is the most versatile all-in-one solution for portable hardness testing. The 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 Equotip Leeb Impact Devices, the 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. 

The new generation Equotip Touchscreen interface is specifically designed to provide an exceptional user experience. The enhanced software provides interactive wizards, automatic verification processes, personalization options and custom report functions. Furthermore, it is compatible with upcoming developments.

The full color display allows best possible measuring and analysis of the measured data. The specially designed housing optimizes the on-site usage of the device in harsh environments.

To date, Proceq’s Equotip has become established as a globally recognized measuring technique and a de facto industry standard. The Equotip devices fully meet the demand for non-destructive hardness testing in a broad range of industries.
