Microhardness Tester VMHT

manual or fully automatic Vickers and Knoop Microhardness Testers UHL-VMHT

The microhardness testers of the UHL VMHT series provide semi- or fully-automatic low-load Vickers or Knoop hardness testing from 1 g to 2 kg.

Using brilliant Leica optics and a high valuable load mechanism with fixed weights to apply the test force, repeatable and long time stable results are achieved.

Even the basic model is equipped with a user friendly motrized turret, an optical focus helper and motorized load selection.

motorized 6x turret VMH-303VMH-303

Motorized turret for 2 indentors and 4 objectives.
All instruments can be optionally equipped with this 6x turret.
This enables the VMHT to do Vickers and Knoop respective Brinell indentations without changing the indentor..



Flexible conversion tables and radius correctionFlexible conversion tables and radius correction

The new versions of our hardness testing applications for VMH-002 to VMH-I04 are supporting now the usage of editable conversion tables
(Standard ASTM E 140: HV, HK, HRC 150, HRD 100, HRA 60, HR 45-N, HR 30-N, HR 15-N).
The curvature / radius of the specimen surface can be considered now, by using a radius correction table accodring to ISO 6507-2.


Scanning and graphical definition of the indentation pattern with VMH-I04Scanning and graphical definition of the indentation pattern with VMH-I04

Single or multiple specimen can be scanned in special holders (accessory) with low magnification.
Various indentation patterns can be graphically defined within the stiched image after the scan by mouse.

The testing results can be shown as color chart in the graphic.
