Color Wheel, NH4 Kit
The unique color disc kits feature a continuous-gradient color wheel for fast, accurate comparisons. The continuous color provides higher levels of accuracy. Kits also use a blank as a reference in color comparison, compensating for color in the sample.
Simply react the sample, then insert the blank and the sample into the holder. Rotate the color wheel to obtain a color match between the blank and the reacted sample. Accuracy for color disc kits is typically ± 10% or ± the smallest increment, subject to individual color perception.
