Features :

  • The independent research and development of lifting system and positioning system, ensured the accuracy and repeatedly of the testing process
  • The optical system designed by senior optical engineer (who worked in the Shanghai Optics And Fine Mechanics Institute, Chinese Academy of Science) not only meet the definition of hardness testing requirements, but also can observe the micro structure of the material
  • With Vickers hardness and Knoop hardness testing capabilities, and testing force can be extended to 2 KG
  • Testing method, testing power and operation time can be displayed directly on the LCD screen
  • The hardness value can be displayed directly by entering the indentation diagonal length and avoid the complication of the look-up table
  • According to different visual habits of the operators, the strength of the light source can be adjusted. To avoid the visual fatigue for long time operation
  • The testing data able to be printed directly by the built-in printer
  • Reserved image channel can be connected with computer, used the image analysis software to analyzing the physical and chemical properties of the material
