I work with plastic injection molded products with material that are similar in color. Furthermore, I need to determine the difference between the two products, and I am looking for an inexpensive way to determine the differences. MSC and Grainger have digital light meters which are inexpensive; however, I am on a limited budget and would rather spend the money on a unit that will work, rather than a product that I hope works. Any feedback would be greatly appreciated.
