Ratio of diagonal measurement is 1:32 versus 1:7 for Vickers. Consequently the indenter does not have to penetrate so much in the material in order to get a readable imprint. <br><br>Clemex can offer fully automatic system for this purpose or a Software kit that retrofit to any tester. <br><br><a target=_blank href="http://www.clemex.com/Company/Contact.aspx">Contact sales</a> for more info.</div><br><br>
