Wide application range

The OmniTest Universal Hardness Tester is designed to meet the increasing demand of versatility for the laboratory or quality control station. The unique design and advanced features eliminates operator influence during indentation measurement, thus assuring the highest repeatability. The combination of cutting edge technology and ease-of-use make the OmniTest with fully automatic image evaluation the obvious replacements for traditional mat-screen testers.
The OmniTest offers a load range between 1 and 250kgf:

Rockwell: 60, 100 and 150 kgf
Superficial Rockwell: 15, 30 and 45 kgf
Vickers: 1-120 kgf
Brinell: 1-250 kgf

Touch screen operation

A large 12” LCD touch screen and intuitive windows style pull-down menus ensures ease of operation. Hardness data and images are automatically saved for statistical evaluation and reporting.

The OmniTest software includes:
• Methods and surface settings
• Hardness conversion
• Manual re-measuring possibilities
• Statistics
• Report templates
• User fields
• User level management

Reporting and statistics

The OmniTest is equipped with USB and RS232 ports allowing the tester to connect to your network for central storage of measurement data or a free standing printer. The USB ports can also be used to connect a mouse or a keyboard. Report templates are available and can be customized to fit your demands. User fields can be defined allowing the operator to enter specific information on samples or test series. The user fields are included in the report. Statistical evaluation of the measurements including minimum, maximum, average, standard deviation, Cp and Cpk can be viewed graphically directly on the LCD screen and included in the printed reports.

Convex and concave surface correction

OmniTest gives you the possibility to correct measurement values for samples with convex or concave surface. Once the diameter of the sample has been defined the Tester will automatically calculate the correction value according to standard.

Fully automatic test cycles

The OmniTest Universal hardness Tester features a fully automatic test cycle, load application, unloading, focusing and capturing of the image (Vickers and Brinell) is performed fully automatic. This greatly improves reproducibility of test results since operator influence is eliminated. The automatic test cycle also saves time and ensures that each test is performed according to the applicable standard.

Innovative closed-loop technology

The OmniTest incorporates the latest load cell technology. The test load is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit. The result is highly accurate measurements at all test loads. The common load overshoot or undershoot as known from traditional dead weight, or open-loop, systems is eliminated. The absence of mechanical weights not only eliminates friction problems but also makes the equipment less sensitive to misalignments caused by vibrations. The OmniTest not only conforms to all standards but offers even higher accuracy.
