Vickers Hardness Testing Machines

Vickers Hardness Testing Machines

 

The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness. The basic principle, as with all common measures of hardness, is to observe the questioned material’s ability to resist plastic deformation from a standard source. The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force.

Features

  • A wide range of test forces from 1.961N to 490.3N* (.2kgf – 50kgf) is available for measuring a wide variety of specimens. The load duration can be set in 1sec increments between 5 and 99sec. The minimum reading of indentation is 0.1. It allows small indentations to be measured with high precision.
    Function: Control unit
  • Back-lit LCD graphic display for Indentation size (D1 and D2), Hardness value and scale, Number of measurement point Test conditions (HV/HK indenter type, test force, load duration), GO/±NG tolerance judgment, Cylindrical and spherical surface compensation and offset
  • Remote control of power turret
  • Conversion to other hardness scales
  • Statistical processing
