an apparatus used for quality control in the plastics recycling industry for quality control of recycled post consumer clear plastics beverage containers by their ultraviolet black light reflected color , and sends information to a personal computer connected by analog to digital port that compiles a report by software in the p . v . c . contaminants content of a grain sized probe sample of ground p . e . t . material . the apparatus has a photomultiplier tube fitted with a filter capable of blocking the nanometer light wavelength region reflected ultraviolet black light color of p . e . t ., allowing the reflected color of p . v . c . to pass through the filter to allow detection and removal of the p . v . c .. the apparatus is able to detect and remove material that is not within a predetermined nanometer region of reflected ultraviolet black light stimulated color , and by computer software generate a report by analyzing analog to digital logic circuit data on the color region content value of the test sample , the apparatus is useful in determining the amount of contaminants in random samples of clear plastic ground containers .
