Digital Rockwell/Superficial Rockwell Benchtop Hardness Testers
The L.S. Starrett Co. has introduced two new digital Rockwell/superficial Rockwell benchtop hardness testers (Nos. 3823 and 3824) with fully automated load/unload procedures and capable of providing highly accurate readings. The new Starrett models utilize a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit instead of traditional dead weights, enabling high accuracy measurements at all test loads up to 0.5%.
