Yxy Spectrophotometer for Traffic Road Sign NS808 

- Special for traffic signs

NS808 Spectrophotometer is special designed for the color measurement of traffic signs


NS808 Yxy Spectrophotometer is special designed for the color measurement of traffic signs. It was researched and developed solely by 3nh independently who owns the complete independent intellectual property rights. Its leading position in the industry is earned by its powerful functions, high accuracy and reliability. NS808 spectrophotometer can be easily used to measure the brightness factor and chromaticity coordinate of all kinds of traffic signal reflection film. Built-in GB2893 safety color and GB/T18833 all kinds of standard color module of traffic signal reflection films, we can choose one according to the requirement. In addition, we can also conveniently customize polygon tolerance they want.

At the same time, NS808 portable spectrophotometer is also widely used in plastics, electronics, paintings, inks, testiles, garments, dyeing, printing, paper, automobiles, medical, cosmetics and food, etc, and other industries. It is also used in some scientific research institutes and laboratories.

NS808 portable spectrophotometer can measure multiple color indexes from many color spaces to get precise measurement like reflectance spectrum. With NS808 Yxy spectrophotometer, we not only do the study of color matching and color management, but also do color quality control. Configured with PC SQCT software, we can connect to PC and get more extension functions.
