Universal Hardness Tester



● XB-OTS-570HAD is a universal hardness testing instrument for the measurement of Brinell, Rockwell and Vickers scale.
● XB-OTS-570HAD equip 7-testing-foce and 5-indenter, it is universal to measure a most of metal material.
● XB-OTS-570HAD dwell time from 2 to 60S can be setup by the “time key” inside the LCD panel, it is much convenient than the setup on the manual hardness tester.
● XB-OTS-570HAD loading ,dwell and unloading is driven by electronic motor automatically , doesn’t need the operator to handle it, it eliminates the human operating error maximum.
● XB-OTS-570HAD doesn’t need the operator to read and check the hardness scale table ,it will compute and display the testing result once press the key of digital length sensor.


  • Surface coating, steel, non-ferrous metals, ceramics, alloys, etc.
  • Heat treatment, carbonization, quenched hardened layer, nitrided layer
  • Small and thin parts
