Fix Rockwell test head to the surface of iron and steel parts to test the hardness by applying magnetic force. Follow Rockwell hardness test method completely and the test condition complies with standard of ISO 6508 and ASTM E 18.

      The magnetic Rockwell hardness tester is mainly applied in on-site quick test body hardness of steel parts. It can be used to test the hardness of steel plate, pipe, axis, mould, huge forgings and huge and medium-size heat treatment parts if surface available. It can also test the hardness of weld joint in boiler, pressure vessels, and pressure pipes. This tester can replace low accurate and reliable Leeb hardness testers. 

Feature & Use

  • Convenient to Use: Attach to one side of part to test, no need to move it.
  • NDT Testing: Quick, convenient, no damage test.
  • Reading Scale: Similar reading system as micrometers, easy to read, and good repeatability.
  • High Accuracy: Rather high accuracy, complying with ISO 6508 and ASTM E18.
