Simply put, Bench Hardness Testers are the most accurate way to measure hardness.  They are considered to perform a "destructive" test because they will leave a small impression on the tested surface.  Capable of measuring with up to 150kg force a bench hardness tester is heavy machine that will need a sturdy bench to support it.  Some models feature both superficial and standard Rockwell hardness testing (twin tester).  Contact us with any questions!  Our technicians will be happy to assist you with your application.
