TFT 3.5 Inch Color Matching Spectrophotometer NS808 for traffic
road sign marking line colour measurement
In the relevant standards such as "GB 2893 Security Color" and
"GB/T 18833 Road Traffic Reflective Film", a color area (multiple
chromaticity coordinate points) and brightness factor requirements
are usually given, in D65/A light source and 45/0. Under the
geometric condition, it is determined whether the sample falls
within the corresponding color region, thereby determining whether
the sample satisfies the standard chromaticity requirement. Since
the color area is a polygon, as shown in the following figure, the
judgment cannot be completed using a normal spectrophotometer. The
NS808 Color Matching Spectrophotometer with the traffic signpost measurement module of the SQCT software
can easily solve this problem.
Product Introduction
NS808 spectrophotometer is developed by 3nh with independent
intellectual property rights. It features with stable performance,
precise measurement and powerful functions in the leading position
of the same industry. It is designed specially for traffic sign.

Advantages of precision colorimeter measurements
People's perception of monochrome changes with the background, the
illumination source, and the emotion of the color measurer itself.
These factors completely affect the accuracy of the results of
color measurement, and people began to use precision colorimeter in
order to improve the correctness and stability of product
measurement. Precision colorimeter has the same sensitivity as the
human eye box, but as the precision colorimeter uses the same
standard light source and lighting environment to measure, the
color information measured by both the indoor and outdoor, day and
night, and the operator is the same. This makes the measurement
simple and accurate and free from subjective factors and external
environment.
In addition, the precision color difference meter can completely
reveal the subtle chromatic aberration problem that is difficult to
be discovered by the human eye. The actual difference between the
two colors is almost the same as that of the human eye. However,
this color difference still exists. In the industry where color
accuracy is not high, these subtle chromatic aberrations may not
have much impact, but in the industry where color quality is
strictly required, such subtle chromatic aberration can be said to
be fatal. The precision colorimeter can perfectly reveal the sharp
color difference. Since the precision colorimeter is used to
measure the result to the operator in digital form, so comparing
the color digital information between the two products makes it
easy to find subtle color changes. Controlling the color details in
production is inseparable from precision colorimeter.
