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.
Durometer Hardness Testers
Measure the hardness of flat materials, such as plastic, rubber, and laminate. For more information about durometer scales, please see the bottom of About Rubber.
Style 3 testers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Digital Durometer Hardness Testers
Measure the hardness of flat materials, such as plastic, rubber, and laminate. For more information about durometer scales, please see the bottom of About Rubber.
These testers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. A maximum-reading indicator holds the highest reading until reset. Use the USB/RS-232 port for direct connection to your PC.
