Accessories for Hardness Testers

Rockwell Hardness Test Blocks
The Rockwell hardness tester measures material hardness by assessing the depth of an indenter's penetration under a load. It's fast, reliable, and uses scales like HRA, HRB, and HRC for various materials, following ASTM E-18 standards.

Indenters for Hardness Testing
Hardness tests assess material hardness by measuring indentations from specific indenters. Buehler offers a range of indenters for Vickers, Knoop, Rockwell, and Brinell scales. Explore our products for details.

Sample Holders and Anvils
Hardness testing requires precise support with sample holders and anvils to secure specimens, ensure stability, and align surfaces perpendicularly to the indenter. Contact Buehler’s lab team for assistance with selecting the right accessories.

GP-HDT Sample Fixture
The GP-HDT sample fixture enables smooth transition from polishing to hardness testing on Wilson testers, improving efficiency. It’s compatible with Buehler central-force specimen holders and integrates seamlessly with EcoMet®, AutoMet®, VH3100/VH3300, and UH4000 series.
