3nh NS808 45/0 Yxy color measurement spectrophotometer for traffic
sign specific purpose
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
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.
