TheCHNSpec 45 / 0 spectrophotometer adopts a measurement structure more in line with human eyes. The 45 / 0 spectrophotometer is specially used for the measurement of such products as road traffic signs and printed matter. This article mainly introduces the application of 45 / 0 spectrophotometer in road traffic signs.

1、 Introduction to road traffic markings

Traffic index line refers to the signs that convey guidance, restriction, warning and other traffic information to traffic participants with lines, arrows, words, elevation marks, raised road signs and contour signs on the road surface. Its function is to control and guide traffic. It can be used with signs or alone.

Traffic marking

2、 Quality requirements

The quality requirements specified in quality requirements and testing methods for road traffic markings (GB / T 16311-2009) are as follows:

3、 Detection method

四4、 Application of color difference meter in surface color detection of road traffic markings

The CHNSpec 45 ° / 0 ° spectrophotometer is a 45 ° / 0 ° spectrophotometer with optical structure. The 45 ° / 0 ° geometric optical structure is consistent with the color value of visual perception. There are up to 23 kinds of observation light sources, including the observation light sources specified in standard D65 road traffic markings.

CHNSpec 45 ° / 0 ° spectrophotometer DS-700C and CS-600C

The following describes the measurement steps of the CHNSpec 45 ° / 0 ° spectrophotometer

Step 1: black and white calibration

Place the test port of the instrument on the black chamber, press the "enter" key for calibration, and complete after a short beep; After the black calibration is completed, put the test port of the instrument on the white board, press "enter" to calibrate, and complete the white calibration after a short beep.

Step 2: standard sample measurement

On the main page, select "setting icon" through the up and down selection keys. Press enter to enter the "setting" interface, select "YXY", then exit the main page to enter the "measurement interface", click the test key to measure the sample.

Step 3: sample measurement

Click "menu" to enter the test sample interface and test the sample.

Test sample

In three simple steps, the values of chromaticity coordinates x and y of road traffic markings can be easily measured, and the brightness factor we want to measure can be obtained by Y / 100. So as to complete the quality detection of road traffic marking color.

Using 45 / 0 spectrophotometer to detect road traffic signs is so simple. This year, the CHNSpec also launched a new 45 / 0 spectrophotometer, ds-700c, which can also meet the measurement of traffic road signs. At the same time, the new 45 / 0 spectrophotometer can also connect mobile app and wechat applet to support data cloud storage. The spectrophotometer is worthy of your possession.
