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 Hardness Tester 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%. The testers are part of a significantly expanded line of new hardness testing solutions that Starrett is now offering.
The Starrett No. 3824 Hardness Tester has an automated Z-Axis. The user simply presses the START key, and the entire test process is automatically completed. The Starrett testers feature programmable scale conversions, dwell times, statistical capabilities and a test counter and are capable of testing in a wide range of 30 different Rockwell hardness scales for carbon steel, alloy steel, cast iron and non-ferrous metals.
