Standard Features

  • Easy to use
  • High repeatability
  • Application range 20 - 80 Shore DO units
  • Certificate of Compliance with the order 2.1 according EN 10204 is included


For measuring the hardness, the spring-loaded outer ring of the housing is pressed downwards until the edge of the ring meets the colored marking on the housing. This ensures a constant pressure and prevents measuring errors.
The principle used to measure shore hardness is based on measuring the resistance force of the penetration of a pin into the test material under a known spring load. The amount of penetration is converted to hardness reading on a scale with 100 shore units.
As the depth of indentation is max. 2.5 mm the testmaterial has to have a minimum thickness of 6 mm. If thickness is less stack some samples til you reach the required thickness.
