World leading product designed and manufactured by our company with patent, because of high-accuracy sensor and unique distance measuring technology, reaching far higher test accuracy than other portable hardness testers. It is fixed onto the surface of a iron and steel part smartly with magnetic chucks. This digital Rockwell hardness tester follows the Rockwell hardness test principle, and complies with relevant regulations of ISO6508, and ASTM E18 standards.


The digital portable hardness tester is mainly applied to test too large or heavy iron and steel parts for the desk testers.


This digital hardness tester is also used to test the hardness of steel parts, bearings, molds; large and medium-sized heating parts.



  1. Attach to one side if part to test, no need to move it.
  2. Quick, convenient, no damage test.
  3. Similar reading system as micrometers, easy to read, and good repeatability.
  4. Rather high accuracy. Complying with ISO6508 and ASTM E18.
