Two digital Rockwell/ Superficial Rockwell Benchtop Hardness Testers (Nos. 3823 and 3824) with fully automated load/ unload procedures provide highly accurate readings. The Starrett Hardness Tester models use 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 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.
Suitable for both internal and external testing via a dolphin nose design, the Starrett No. 3823 and 3824 Digital Testers are high-precision testing solutions that meet ISO 6508-2 and ASTM E18 standards. They feature a built-in micro-printer, touch screen control on a high-definition LCD display, USB output, and are furnished with PC-based software. For memory, a maximum of 400 items of test results are stored automatically. Testing capacity is 12 in. (300 mm) vertical and 8.8 in. (220 mm) horizontal. A full range of accessories from test blocks to anvils, to dust covers are also included.
