Pressure-Grip Rockwell Hardness Testers
Operate these testers with one hand. Squeeze the handles until the penetrator contacts the test material and a reading appears on the dial indicator.

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.

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.
For heat-treated material harder than Rockwell C20, use the optional C-scale diamond indenter.
