In a metal with the same hardness we will have a different values of this stress. Therefore, the problem will be to measure the values that vary so exactly proportional to the residual stress values in a given metal. </font></p><p><span lang="EN-US" style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Verdana"><font size="+0"><font face="times new roman,times,serif"><br />You will realize the convenience of this apparatus.</font></font></span><span lang="EN-US" style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Verdana"><font size="+0"><br /><font face="times new roman,times,serif"><strong>1</strong>) <u>Portable and easy to use and very rapid. measuring point to point.high accuracy.&#xa0;</u></font></font></span><span lang="EN-US" style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Verdana"><font size="+0"><u><br /></u><font face="times new roman,times,serif"><strong>2</strong>) <u>NDT/NDE non-destructive</u></font></font></span><span lang="EN-US" style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Verdana"><font face="times new roman,times,serif" size="+0"><u>testing.</u></font></span><span lang="EN-US" style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Verdana"><font size="+0"><font face="times new roman,times,serif"><strong>3</strong>) <u>Repeatable in unlimited number of times</u>.<br /><strong>4</strong>) <u>Not dangerous</u> (X-ray). <br /><strong>5</strong>) <u>Do not expensive</u>.
