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.

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.
