FAQs About  SFRPlus Test Charts

Use our 3nh company approved light. Replace all of the same type together and recalibrate to keep consistent color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses


Standard light sources make sure that the results of color evaluations are comparable and consistent, no matter when and where the assessments are made, or the varying production runs.


Plastics, glasses, films, coatings, PET carboys，and packaging materials are common uses of hazemeter to monitor consistency and quality.
