Portable Rockwell hardness tester for scratch-sensitive, polished and thin parts. It features excellent sensitivity through small penetration of a few micrometer. Rugged touchscreen with enhanced software features and analysis functions.

The test principle of the Equotip Portable Rockwell follows the traditional Rockwell static test method. During measurements with the Equotip Portable Rockwell Probe, a diamond indenter is forced into the test piece using a precisely controlled force. The indentation depth of the diamond is continuously measured while a load is applied and released. From the indentation depths d1 and d2 recorded at two defined loads, the difference is calculated: Δ = d2 – d1 . This is traditionally referred to as plastic deformation.
