The Newage® MT91 Automatic Microhardness Traverse Testing System offers unrivalled testing speed – as fast as six seconds per test cycle—and a precise Rockwell type testing method that requires no manual interpretation of the impression.
The MT91 measures hardness based on depth of penetration rather than using an optical system that determines hardness based on impression size. No traditional microhardness tester comes close to matching the MT91 in terms of speed or accuracy. Tasks that once took hours now take only minutes, and individual test cycles can be completed in just six seconds, making the MT91 the perfect choice for high-volume applications.
The modular Newage MT91 System is a cost-effective solution for applications that require advanced microhardness functionality, such as complex case depth traverses. The system consists of a MT91 microhardness tester with video camera, combined with a personal computer, a motorized X-Y axis positioning table and Newage’s proprietary C.A.M.S.® (Computer Assisted Measurement System) software.
The system’s video camera views and defines test measurement locations and traverse procedures. The C.A.M.S. software operates the test head and motor control system to accurately position test samples and perform measurement cycles. Compared to automated optical microhardness testers, the MT91 is less dependent on surface conditions. It has no difficulties with dark spots or varying light levels on the test samples that can occur with optical systems. It also can be used to test etched parts or measure surfaces prepared to 400-grit polish.
Case depth comparison is considerably easier using the MT91 system than a traditional optical system. Operators can quickly and easily set up complicated staggered traverse procedures with the graphical set up utility. The MT91 then performs the traverse routine accurately and repeatedly, and calculates the sample’s case depth. Up to 24 traverses can be setup as part of a single procedure.
The MT91 C.A.M.S. software complements its advanced video capabilities with comprehensive test setup tools, including intelligent prompts and menus that guide the user through the test configuration process. Once the setup is configured, the MT91 system provides users with a variety of on-screen navigation tools. Its on-screen analysis is exceptional. A comprehensive display shows hardness results, converted values and tolerances at a glance. Operators are able to orient the traverse direction to each test part on screen within seconds.
