HR-320MS/430MR/430MS – Series 963 – Rockwell Hardness Machines

Features

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
