Static and Dynamic
For the first time, the MIC 20 of Krautkramer combines the methods of quasi-static UCI hardness test and dynamic rebound: the MIC 20 places now "hardness testing in a twin pack" at your disposal with these two different physical methods - and covers its entire range of applications.
This makes the MIC 20 a universal instrument: you can use it to test fine-grained materials with pasta and different shapes or surfaces with heat treatment (UCI method) and also components, forgings and large cast materials and coarse-grained (method By rebound).
The UCI method (Ultrasonic Contact Impedance, ultrasonic contact impedance) determines the hardness of a material based on the size of the indentation left in the material testing by a Vickers diamond after applying the test load.
In the case of rebound method, an impact body is propelled by spring force against the test surface. Impact speeds and rebound are measured without contact; the hardness value is calculated from these two values.
The MIC 20 automatically adjusts to the corresponding method so that one is connected UCI probe or an impact device for rebound.
Key Features and Benefits
Use Easy Oriented Course
MIC is one of the characteristics 20. You can directly see the indicated measured value according to the hardness scale selected in the large color LCD or color TFT display.The graphical user interface shown in the display is adapted to the known Windows standard and its presentation is intuitive. You do not need a mouse to operate, only a stylus to tap on the touch screen and set the functions.Alternatively, there is also conventional buttons available for most configurations.
You will soon be familiar with the operating concept: three main menus ensure easy access to crucial functions - there is no way to get lost in a maze of menus!
The MIC 20 facilitates, for example, the calibration for you.The configuration parameters are then simply filed and recalled by pressing a button or a click on the corresponding application box.
A direct memory data enables the convenience and structuring in saving and management of test results. The MIC 20 also presents the necessary functions for your analysis: You can view a series of measurements as a curve, histogram or table with statistics.You can use, for example, the standard Windows applications for processing, evaluation and subsequent statistics.
Use in Local
with the mobile and flexible MIC 20, you surely will like it: in addition to an electrical connection, the instrument is operated through our rechargeable battery pack, which allows the internal loading on the instrument. The display is switched off after a certain period of time and can be reactivated by a touch on the screen. You can also automatically trigger a full shutdown after a preset period of time - which ensures operation with energy savings.
