Hardness testing and analysis

In addition to our range of hardness testers, we have two options for combining hardness testing with indent analysis:hardness testing

If you already have a hardness tester and want to upgrade your analysis and improve the statistical reliability of your indenting process, then our recommendations would be to retro-fit Clemex CMT lite.

Alternatively if you are looking for a fully automatic hardness testing and analysis tool, then you need Clemex CMT.HD

Clemex CMT - retro-fit hardness testing image analysis

If you already have a hardness tester then Clemex CMT may be the solution for you.

hardness testing
It can be retrofit onto virtually any tester and can be supplied with PC or laptop. In addition to the high resolution camera all the cables and adapters needed are supplied, so it is up and running right out of the box.

In just 4 steps, you can have statistically valid results:

Step 1 - see the entire sample
Place the sample in the sample-holder or just flat on the stage platen.
Build single or multiple traverses/patterns.
Clemex CMT.Lite will tell you exactly where to position the stage micrometer to follow horizontal, vertical and even angled traverses.

Step 2 - position the indent.
Position the stage precisely using Clemex CMT’s built-in cross-hairs and then make the indent.

Step 3 - measure.
Rotate the turret to the measuring objective and click on the Measure button.
Results are automatically tabulated.
Clemex CMT not only offers higher resolution images than the competition, it can also compare how sharp an image is compared to previously viewed images. In addition, the Focus Meter takes the subjectivity out of focusing the image and provides the sharpest image possible.


Step 4 - get the results.
Review the results in graphical and/or tabular format. Export results to the spreadsheet application of your choice, or simply print standard or customised reports.

Automatic hardness testing and analysis - Clemex CMT.HD

The Clemex CMT.HD is probably the best fully automatic micro- and macro-hardness testing solution on the market.hardness testing

If you need intelligent workflow: i.e. set up the traverse pattern and leave the equipment to auto-focus, measure and report without further input, then this is the system for you.

In 4 easy steps you can set precision indent patterns thanks to CMT.HD's integrated macro-view analysis and layout tools.

In addition to standard patterns, you can create and save up to 99 patterns of your own each with up to 32000 indents.
This means that no matter the shape or size of your sample, it can be tested in reliable, accurate and repeatable way.

Step 1 - place the sample in the holder and click to acquire the macro view.hardness testing

A high definition image of the sample appears on screen no-matter the size of the sample.
Options include an aerial view, close-ups and a global view
This enables you to set up multiple reference points for traverse patterns.

Step 2 - select or create traverse patterns or recall and alter previous ones.

You can use the conveniently located annotation tools to find the centre of the sample, draw straight and parallel lines, add ticker marks, produce multi-directional patterns and create indent traverses at a certain distance from the sample edge.

Or simply use the Free-run function and an automatic pattern will be created and processed in the results window.

Step 3 - click and walk away.

CMT.HD will follow the patterns created, auto-calibrating and re-focusing itself as it does so, leaving the operator free for other tasks.
The system's 1.3 megapixel camera produces high resolution images which surpass the detail of any of its rivals by over 300%.
The indent diagonals are based on the precision stage micrometer. Together these, features ensure the sharpest images and finest detail micro-hardness testing.
Measurements are repeatable because the software controls focus at 0.1micron steps, corrects shading and the lightsource regardless of the number of indents.
Its auto-detection capabilities mean that the CMT.HD can measure indents on any sample surface be they etched, roughly polished or clean.

Step 4 - get the results.

These are available in tabular or graphical format, and can be exported to your own spreadsheet package or the purpose built custom reporting package.

In addition to its perfectly accurate, repeatable hardness testing, CMT provides you with the tools to conduct: grain size analysis, analyse particles, calculate phase area percentage and evaluate layer thickness of multiple layers.

Naturally, in addition to its unrivalled accuracy, this range of hardness testing system is fully ASTM E 384 and DIN/ISO 6507 compliant. It also has multiple samples holders with and without testing blocks, and vices to hold unmounted samples.
