The PHR Series portable Rockwell hardness testers of TianXing have brought a revolution to the traditional means of hardness testing. Weighing only one hundredth of a bench-top Rockwell tester, they can be easily used like a micrometer.

The portable Rockwell hardness testers have the same precision as the traditional bench-top testers, and are very easy and simple to use. Vertical testing force is no longer required, and it takes only 10 seconds to complete a single test.
