The FH-31 Series is a new generation of hardness testing instruments. The main body is a precision cast rigid structure and incorporates a load cell-based, closed loop force loading actuator to provide precise, adjustable loading on the indenters. The load application system avoids ‘overshoot’ during the test and guarantees one of the best GR & R results ever seen on Rockwell/Brinell hardness testers in this class.

The tester meets or exceeds the ISO, ASTM and JIS standards. (ISO 6508, ISO 2039/1, ASTM E18, ASTM B254, JIS Z2245). Test forces range from 2.5-187.5kgf, which means that even this basic model is equipped with Rockwell, Superficial Rockwell and Brinell load settings (model dependent). System control is managed by a 6.5 inch industrial touchscreen running our Horizon firmware, but a mouse and keyboard can also be used. The touchscreen will also display results and statistics.
