Mitutoyo Series 963 Rockwell Hardness Tester HR-430MR - 963-240-11A
- The new frame design alllows the full 7.1” of specimen capcity without the need to cut a whole in the table.
- Simple to operate; The digital HR320 model uses a flashing bar graph to indicate when the initial test force has been reached.
- 430 models feature 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.
These new hardness testers include a smoother operating elevating screw, warning buzzer, cylindrical part corrections and adjustable RS232C baud rates. Testers now come complete with certified indenters and test blocks.
