Hardness tests are always an issue and here we can fall back on the MIC 10.

We are using an UCI (Ultrasonic Contact Impedance)

  • Hardness testing on site according to the UCI method (Ultrasonic Contact Impedance)
  • Standardized according to ASTM A 1038
  • Probes with test loads from 1 N (HV 0.1) and 98 N (HV 10)
  • Automatic conversion into different hardness scales and tensile strength (only 98 N-probe)
  • Display of individual values or averages of a series of tests
  • Data logger versions with internal data storage for data and device settings

Test Methods:

Hardness testing with Vickers indenter (126° diamond pyramid), evaluation of the test indentation under load.


With this tester, the hardness of rubber can be determined. The accuracy is 0.1 hardness units.

  • Can be used both mobile and stationary
  • Compliance with all current standards of hardness tests
  • Holds the maximum value (peak hold)
  • Suitable for single and series measurements
  • Data transfer to PC or laptop possible

Krautkramer TIV Hardness Tester

Using a special lens, the innovative TIV method (Through Indenter Viewing) uses a direct optical evaluation of the diamond according to Vickers indentation under load. The image of the impression is transmitted to the display device and is evaluated automatically.

  • Hardness testing according to Vickers under test load
  • Look through the Vickers diamond using a special optical system and a CCD camera
  • Direct control and evaluation of the quality of the measured value by checking the impression on the color screen
  • Fully automatic evaluation of the diamond indentation and immediate determination of the diagonal lengths
  • Independent of the test direction and the material of the specimen
  • Measuring range is from 30 HV up to over 1000 HV (depending on probe)
