Portable Rockwell Hardness Testers

Standard Metal Hardness Testers

Superficial Metal Hardness Testers

Simply The Best.

Each Ames Rockwell hardness tester is built one at a time in our US facility.  They’ve been manufactured under the Ames name for over 60 years and under the Electro Arc name for 45 plus years.  Our testers meet the military requirements of MIL standard 45662A.  Each certificate comes with traceable certificates for the tester, test blocks, diamond and ball penetrators.  Our lightweight Ames precision hardness tester has a “Y” configuration and is simple in appearance.  The case is comparable to the size of a propane torch kit and comes with certified test samples for confirming the tester’s continued accuracy.  It takes actual Rockwell hardness readings conforming with the ATSM standard E-18 not a conversion.
