Review on Portable Analyzer Colorimeter Difference True Color by Drew Gengler

I needed a sensor to check the dry film color on our customer approved coupon products. I gave this item (4) stars because the sensor takes the reading from the approved coupon and compares it to the product sample. This seems to give a fairly accurate reading/comparison. I would give (5) stars if the sensor actually reported the exact same readings with a slight deviation from the claimed approved coupon. Comparing one color to another completes the process again.
