(The L.S. Starrett Co.: Athol, MA) -- The L.S. Starrett Co., a leading global manufacturer of precision measuring tools and gages, metrology systems, and more, has introduced two new digital Rockwell/Superficial Rockwell Benchtop Hardness Testers (No. 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 percent. 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 nonferrous metals.
