GE Krautkramer MIC 20 Portable Hardness Tester NDT

After decades of manufacturing the GE Krautkramer MIC 20, GE has now exited the UCI hardness market. The new replacement for the GE Krautkramer MIC-20 now comes from NewSonic, a company comprised of former GE Krautkramer Engineers who used to work on the MIC-10 and MIC-20. Their line of SonoDur hardness testers now offers the best, most advanced and improved UCI hardness testing solution currently available. To see the NewSonic UCI hardness testing solutions.

MIC-20 Ultrasonic Contact Impedance & Rebound Hardness Tester

One instrument two test methods a thousand and one applications.

The MIC 20 is able to measure hardness using the UCI method as well as rebound hardness method.  This makes GE Krautkramer MIC 20 an universal instrument able to measure heat treated as well as cast materials.

The Ultrasonic Contact Impedance (UCI) method measures hardness based on the size of an indentation from a Vickers diamond while rebound testing measures hardness by having an impact body impelled against the test surface.  The ability to use both of these methods makesGE Krautkramer MIC 20 a flexible and complete solution for operators.

Static plus dynamic.
For the first time the Krautkramer MIC 20 combines the quasi-static UCI and the dynamic rebound hardness testing methods: the MIC 20 now places “hardness testing in a twin pack” at your disposal with these two different physical methods – and covers their complete application range.
This makes the MIC 20 a universal instrument: you can use it to test fine-grained materials having different masses and shapes or heat treated surfaces (UCI method), as well as large, coarse-grained components, forgings, and cast materials (rebound method). Conforms to ASTM A1038 (latest revision) UCI METHOD

The two methods.
The UCI method (Ultrasonic Contact Impedance) determines the hardness of a material on the basis of the size of the test indentation left behind in the material by a Vickers diamond after applying the test load. In the case of the rebound method, an
impact body is impelled by spring force against the test surface. The impact and rebound velocities are each measured in a non-contact mode; the hardness value is calculated from these two values. The MIC 20 automatically sets to the corresponding method as soon as you connect a UCI probe or a rebound impact device.

The double benefits.
The two methods enable you to easily measure the hardness of your test object in a matter of seconds: place probe or impact
device on the test object, and read the measured value on the display. In this way you can measure anywhere and in any direction. We have used a patented signal processing to also put this advantage into practice for the rebound hardness method.
In addition, the following applies to the two test methods: easy and fast calibration capability, presentation of the results
according to the usual hardness scales, extremely easy handling in mobile use in daily testing situations.
