Product information

  • Accurate Determination of the Gardner Scale
    The AF 228 incorporates 18 glass standards which make up the scale in a pair of discs
  • Fast Determination of Color Value
    You can directly compare the sample with the color values for quick results.
  • Easy to Achieve Optimum Color Accuracy
    The advantage of a 3-section field of view is that the sample and two consecutive glasses on the color scale are viewed simultaneously, making it easier and quicker for you to achieve the ideal color match.
  • Facilitates Tolerance Level Setting
    For rapid color grading within predetermined color limits, the glass standards can be set to the two limiting colors so that it is easy to check that the sample is within tolerance.
  • Guaranteed Constant Lighting Conditions
    In the instruments, the tungsten halogen light source is color corrected to CIE standard illuminant C*, which guarantees constant lighting conditions for color grading.
  • Compliance to Standards
    Each Comparator 3000 is supplied with the correct cells for the appropriate path length determined by the standard.
