Digital Vickers Hardness Tester MHVS-10

Micro-Vickers (or Knoop) hardness test principle is that put the provisions of the positive pyramid diamond indenter into the sample surface(with fixed experimental force) and maintain a certain length (holding), and then unloading. Finally, there is a positive quadrangular pyramid or kenup indentation with a square surface on the surface of the specimen. Then we can attain the area of indentation via measuring the length of the diagonal by a micrometer eyepiece. Then the corresponding Vickers (or Knoop) hardness values are obtained.

Usually Vickers hardness values can be converted according to the following formula

×test force / indentation surface area≈0.1891 F／d2  

Note:

HV, Vickers hardness symbols   

F, test force   

d, the arithmetic mean of of the two diagonal d1, d2
