Portable Rockwell Hardness Testers
 |
Test hardness right on your production floor. Unlike benchtop testers, these portable ones don’t require you to move large or hard-to-access parts. They use an indenter to measure the hardness of aluminum, brass, and steel. These testers can be used at any angle without affecting accuracy.

Rockwell Hardness Calibration Test Blocks
 |
Make sure your hardness testers are accurately calibrated. Blocks are marked with their corresponding Rockwell hardness and a serial number.
All blocks come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.
