Product Description

GE Inspection Technologies MIC 20 Hardness Tester

Hardness tester for quasi-static UCI & dynamic hardness testing according to the rebound method, formerly the Krautkramer MIC 20
The GE Inspection Technologies MIC 20 Hardness Tester (formerly Krautkramer MIC 20) is a versatile two-in-one tester combining the ultrasonic contact impedance (UCI) and rebound test methods. The UCI method 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 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.
GE Inspection Technologies MIC 20 Hardness Tester Applications:
UCI Hardness Testing:
  • Ready-assembled machines
  • Heat-affected zone of a weld (e.g. pipeline)
  • Heat-treated surfaces (e.g. tooth flanks)
  • Coatings(e.g. rotogravure cylinders)
Rebound Hardness Testing:
  • Machine parts or motor units made of steel and cast aluminum alloys
  • Solid, coarse-grained components having a surface as rolled
  • Large series parts during production
  • Heavy forgings
  • UCI is better for small & complex shaped fine-grained metals
  • Standardized to ASTM A1038
  • Rebound is better for larger, coarse-grained forgings & castings
  • Standardized to ASTM A956
  • Internal data memory for approx. 5,000 measurements
  • Automatic scale conversion to HV, HB, HRC, HRB, HS, HL and N/mm²
  • 20 to 1740 HV range
  • Large color TFT display
  • Probe kit required
  • Find options in the accessories tab
Included :
  • Operating manual
  • Carrying case
  • MIC 20-BAT NiMH rechargeable battery pack
  • AC power supply / NiMH pack charger (100 to 240 VAC, auto sensing)
