The Clark CLC-200R is one of the most versatile and easy to use Rockwell type testers available. It uses direct loading, state of the art load cell technology and direct linear displacement that’s activated by simple touch-screen operation. All Rockwell scales, regular and superficial, are fully automatic. And errors have virtually been eliminated by removing the use of knobs and stacking of weights typically associated with most testers. Simply input the scale on the touchscreen and let the tester do the rest.
