  • Standardized automatic length measurement function using a CCD camera built in a novel G frame
  • Easy-to-use software

System Functions

  • The test force is applied with an indenter of diamond quadrangular pyramid with a facing angle of 136 °. The definition of Micro Vickers Hardness value is the test force divided by the surface area of the indent after unloading.
  • Formula：HV＝Test force（Kgf)/Surface area of the indent＝0.1891F/d2
    Expression：704HV0.1/15 (Hardness value 704. Measured at a test force of 0.9807 N (100 gf) and a holding time of 15 s)
