TIV (Through Indenter Viewing)

The TIV hardness tester allows for fast and easy determination of surface hardness with no calibration required. It is also useful in the aviation industry, enabling on-site hardness testing on thin-walled components and on different alloys without additional calibration.

The TIV (Through Indenter Viewing) method is based on hardness testing according to Vickers; makes it possible to “see through” the Vickers diamond by means of special optics. The hardness is measured under load; as soon as the test load is reached, the image of the indentation is transferred and evaluated directly, automatically, and quickly.


  • Through Indenter Viewing method
    -The TIV hardness tester can be used irrespective of the material – without any additional calibration. You can use the same instrument to measure the hardness of all sorts of materials without any reference specimens and without any laborious settings: from steel and nonferrous metals through plastics, carbide metals, glass, and ceramics up to different coatings.
    The static application of the test load reduces the vibration of the test object and therefore the influence of the test material’s elastic properties on the test result. Yet another benefit: you can use the TIV to measure even very thin test objects, such as coils or sheet metal and metal foils, on which stationary or mobile hardness testers have previously failed, without any problem. Consequently, hardness testing becomes independent not only of the material but also of the mass and geometry of the test object. This means that the TIV opens up new application fields for mobile hardness testing.
  • Direct, Automatic & Fast Measurement and Evaluation
  • As the first portable instrument ever, the TIV does not determine the size of the indentation of the Vickers diamond, and consequently the hardness of the material, indirectly but directly: ”Through Indenter Viewing” means that you can see the indentation of the Vickers diamond "grow" on the surface of the test object at the same time as the test load is applied – this is ensured by special optics and a CCD camera. As soon as the test load is reached, the indentation is automatically evaluated and transferred, which means that the diagonals are directly determined, without making a detour via a measuring microscope. Your benefits: the measurement is not only faster but also excludes subjective errors in the determination of diagonal lengths. Plus: by representation on the display, the TIV is the only hardness tester to enable direct control and immediate evaluation of the measurement quality. In addition, the image of the indentation enables direct recognition of the diamond's condition.

  • Unique Technology

  • The color LCD of the TIV hardness tester does not only show you the image of the diamond’s indentation but also the directly displayed reading in the selected hardness scale. The graphic user interface shown on the display is adapted to the known Windows standard. In this way, you will swiftly have a good grasp of how the instrument should be operated, irrespective of if you want to configure, measure, evaluate, or store. The special extra: You do not need a mouse to select functions because the instrument has a touch screen capability using a pen. However, as an alternative, conventional pushbuttons are also available for most of the functions.

Key Features & Benefits

-Hardness Testing according to Vickers under test load
-Through Indenter Viewing by means of special optics and a CCD camera
-Direct checking and assessment of the quality of measurement by observing the growing indentation on the color display
-Fully automatic evaluation of the Vickers indentation and determination of the diagonals without detour (via microscope)
-Independent of test direction and test object's material
-Measurement range from approximately 30HV to more than 1000HV (depending on probe)
-Clearly arranged data memory for convenient and structured saving of the test results. Test series can be recalled and edited.

  • Easy Operation
  • Three main menus make it easier for you to access the most important instrument functions – and you’ll always reach your destination by just a few ”screen clicks”. Do you want to see your test series as a curve, histogram, or statistics? A click is all it takes. The conversion is just as easy for you by selecting another hardness scale. In the menu ”Data”, you can store your results plus image of the indentation in an easy and straightforward way.

  • Mobile Practice
    -You can operate the TIV both with a main connection and with standard cells, or by means of our rechargeable battery pack which allows charging inside the instrument. After a certain period of time, the display goes off, and it can be re-activated by simply touching the touch screen. An automatic switch-off function is triggered after any variable period of time – all data and settings are of course maintained.
