NS808 Spectrophotometer
- Special for traffic signs

NS808 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 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 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 can measure multiple color indexes from many color spaces to get precise measurement like reflectance spectrum. With NS808, 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.
SQCT software is different from SQC8 software for NS series. It has built-in color code of GBT18833-2012 and GB 2893-2008. Customers can choose the color according to their requirement.
