The model FH31-2 combines today’s load application technology with a top class depth measuring system. Rockwell, Superficial Rockwell & Brinell scales are part of the machine’s capabilities. Highly accurate test results and fast operation make it the best in its class today. This model provides a smart user interface, easy to learn and with internal and external data storage options.
Test forces range from 1-250kgf, which means that even this basic model is equipped with Rockwell, Superficial Rockwell and Brinell load settings. System control is managed via a simple-to-use 6.5in full color industrial touchscreen. The touchscreen will also display results and statistics.


The model FH 31-3 is a new generation of hardness testing instrument with protruding nose design. This long nose design allows you to reach as far as 150mm inside a bore or just on flat material similar to any other Rockwell hardness tester. It has working height of 400mm and throat depth of 200mm and can also be optionally equipped with an automatic spindle. Simply push START and the full process of lifting, clamping and testing takes place without operator interference.

  • Twin-scale Rockwell machine that also provides the option for Brinell testing
  • Easy to use, excellent workpiece overview
  • Test forces range from 1-187.5kgf, which means that even this basic model is equipped with Rockwell, Superficial Rockwell and Brinell load settings
  • System control is managed via a simple-to-use 8.5in full color industrial touchscreen that will also display results and statistics
