Universal hardness testers are in fact hybrid instruments allowing the user to carry out Rockwell, Vickers and Brinell hardness tests according to the applicable ISO, ASTM and JIS standards, with one single machine. Universal hardness testers do not convert hardness values but apply tests in each scale according to the standard procedures applicable for such a scale.
While most hardness testers in particular measure only one kind of scale either Rockwell or Vickers or Brinell, Universal testers cover a wide range of test loads and measurement procedures. Convenient for the user that does not need to change its set up for testing one part with different methods and cost reduction as only one tester needs to be purchased, calibrated and maintained.
While traditional Universal hardness testers were complex mechanical structures, built of many parts and complicated weight stacks, newer generations based on load cell technology and closed loop force feedback systems have taken away most of the complexity of earlier models.
Nowadays, Universal hardness testers offer the user the comfort of having one single tester covering all scales.
The advantage is obvious; While Universal hardness testers are often a more expensive asset, money can be saved on maintenance, after sales service and calibration. Due to technology of the load application system, closed loop Universal hardness testers offer a wide range of test loads generally superseding single scale testers traditionally having dead weight load application systems.
We welcome your special attention for the NEMESIS 9100 series as a unique in its class machine, offering a load range of 200gf up to 3000kgf in a single hardness tester.
