Hardness tester is universal

Universal hardness tester has expanded the capability of a special steelmaker's laboratory to carry out Rockwell, Vickers, and Brinell tests, using a revolver system with four indenters.

Deutsche Edelstahlwerke in Stuttgart, Germany, offers its customers a 'one-stop-shop' for heat treatment processes including plasma nitriding.

The company serves leading Major German automotive sports car manufacturers.

Zwick said it was proud to have equipped the laboratory with all of its hardness testers - the most recent being the premier ZHU250 TOP Universal Hardness Tester.

This machine has expanded the capability of the laboratory to carry out Rockwell, Vickers, and Brinell tests, and includes an innovative revolver system incorporating four indenters.

Similar systems require three or more objective lenses to cover the application range but, due to Zwick's unique digital zoom technology, the ZHU250 requires only two.

This enables a fast throughput of tests, and many different types of test can be carried out on the same machine with very high accuracy and repeatability.

The test results are also sent to the host computer system via a computer interface.

"A major reason for purchasing the ZHU250 was the excellent manufacturing quality, and the reliability of our existing Zwick Roell products.

This convinced us to purchase this new machine, and as a result we have saved cost, improved our throughput and increased our business significantly," explained Wessel Voelcker, Deutsche Edelstahlwerke 's production manager.
