Model No. 900-340
With the same rugged engineering of our Rockwell hardness tester, the 900-340 superficial Rockwell hardness tester delivers unmatched repeatability in all superficial Rockwell scales. Used for testing thin and soft metals, this hardness tester utilizes a motor driven system for control of the major test force application. State of the art design and dynamic precision provide highly sensitive and accurate readings. Conforming to ASTM E-18 standards, this hardness tester is suited for tool rooms, workshops, laboratories, and inspection labs. Lifetime Free technical support is included with all of our hardness testers.
