steps of test force between 1 and 2000p (gf) selected at the touch of a
button. A newly
introduced focus finder is available enabling the operator to detect
the focus very quickly. Approach velocity of the indenter can be
selected between 25 and 60 μm/s. Infinity corrected Leica Plan objectives
from 10X to 100X with a measuring eyepiece field of view of 16mm. For each test the measured diagonal
lengths and hardness value for given test forces are stored as well as
tolerance and statistics. All models are equipped with a motorised
turret making operation quick and simple. Printer and PC interfaces – RS232, Centronics, USB and Ethernet are offered. |

VMHT AUTO |
| Ideal
for high capacity production sites.
Orientate the specimen on a fully motorised stage and call
up the test parameters using interactive software.
The system performs the measurements fully automatically
without any further attendance. Sample thickness does not have to be
parallel since three z-positions can be defined using the autofocus to
do the area alignment. Data can be stored and retrieved and
displayed on one screen. |

| Intuitive user
interfaceThe colour touch-display has a clear and easy
user interface. All settings can be done by touching the desired value
or function.Display of ResultsResults for one or multiple specimens are shown in tabular form or graphically together with all necessary testing parameters.Values within the tolerance are shown green, values out of tolerance are shown red. Integrated statistic functions are used for data evaluation. The CHD hardness depth (in mm) can be determined. The graphs can be directly printed or saved on a USB memory stick. Integrated Video FeatureThe system is equipped with an optional high resolution digital video camera.The video image is shown directly on the touch-display and can be saved on a USB memory stick or printed. An optical and electronic focus finder with peak display makes focusing easy and repeatable. |
| Upgrade
Existing Hardness testers |
| All
manual hardness testers with a c-mount camera attachment can be
equipped with a USB camera (VM4-USB). In combination
with this camera a measuring software for measuring the hardness by
horizontal and vertical lines and saving the video images is available:
VMS-VMH. This is an affordable solution to upgrade old
hardness testers of any brand to convenient video technology. |
