The Rock 3 is the Entry Level Rockwell tester in the Ernst by King line. This machine is ideal for various volume, accurate testing on all scales.
The Nose Piece serves as a reference point during testing to compensate for any deformation of the machine or the test piece that would otherwise effect the result. This reduces operator error and provides consistent and accurate results with minimal test piece preparation and operator training.
Test times as low as 4 seconds increases efficiency in the lab as the preload and load are applied through one pull of a lever.
Meets ASTM E 18, ASTM D-785 & ISO 6056
Interchangeable heads for Rockwell and Superficial Rockwell testing
Easy pre load & load application
