Mitutoyo HR Series Rockwell Hardness Tester HR-430MS - 810-194-21A
Features:
- The new frame design allows the full 7.1" of specimen capacity without the need to cut a whole in the table.
- Simple to operate; the Dial Type HR210 features an automatic zero reset. The digital HR320 model uses a flashing bar graph to indicate when the initial test force has been reached.
- Automatic brake and automatic start function that prevents overloading and begins test cycle. The HR430 model also includes the dial a weight system for easier load selection.
- All models are complete with Flat and VEE anvils, diamond and 1/6" carbide ball indenters, 2 HRC and 1 HRBW Rockwell blocks (MR models)s or 3 Rockwell blocks and an HR30N and HR30TW for MS testers
