NS808 Traffic Sign Colorimeter Introduction: In relevant standards such as GB 2893 Safety Colors and GB/T 18833 Road Traffic Reflective Film, a color area (multiple chromaticity coordinate points) and brightness factor requirements are usually given. Under D65/A light source and 45/0 geometric conditions, it is determined whether the sample falls within the corresponding color area to determine whether the sample meets the chromaticity requirements specified in the standard. Due to the polygonal color area, as shown in the following figure, it is not possible to complete the determination using a regular spectrophotometer. The NS808 colorimeter combined with the SQCT software's traffic landmark measurement module can easily solve this problem.
