Spectrophotometers Road Marking
The BT808 special spectrophotometer for traffic road signs is equipped with D65/A/C/F2 and other light sources. The geometric light path structure is 45/0 (45 ° circular uniform illumination 0 ° reception). This instrument can conveniently test the brightness factor, chromaticity coordinates, CI E L * a * b and other chromaticity data of various reflective films; It is widely used in road traffic landmark testing, plastic electronics, paint and ink, textile and clothing printing and dyeing, printing paper, automobile, medical treatment, cosmetics, food and other industries, and in scientific research institutions and laboratories.In GB 2893 Safety Color, GB/T 18833 Reflective Film for Road Traffic and other relevant standards, 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, so as to determine whether the sample meets the chromaticity requirements specified in the standard. Because the color area is polygonal, as shown in the figure below, it is impossible to complete the determination using ordinary spectrophotometer. NS808 colorimeter and SQCT software's traffic landmark measurement module can easily solve this problem.
