With the development of society and the improvement of living standards, cars as a means of transportation are becoming more and more popular, and the number of cars is increasing sharply. As a result, people who often need to cross the highway or work on the highway for a long time, such as cleaners and traffic police, are facing increasing risks.  In order to effectively reduce the occurrence of traffic accidents, it has become imperative to wear warning clothing made of special materials to such people, or to add special warning signs to people's clothes, roadblocks and warning signs.  In this way, whether it is under harsh light during the day or under the irradiation of dim lights at night, the driver can be sure to find pedestrians or roadblocks and warning signs in time, and the driver will have enough time to brake or turn to avoid accidents.  Whether warning clothing or warning signs can be found in time in a specific environment or at a specific distance becomes a crucial factor to avoid traffic accidents.  "Retroreflective Coefficient Tester" simulates whether the light intensity fed back from the vehicle driving at night under the specified standard light source, distance and angle meets the requirements of GB206532006, GB/T284682012 and other standards, thus effectively evaluating and judging the warning signs.  FFZ432 retroreflective coefficient tester produced by Wenzhou Fangyuan Instrument Co., Ltd. is divided into manual measurement and automatic measurement. Manual measurement can be used to quickly measure a certain incident angle and observation angle.  The automatic test can carry out comprehensive measurement for 16 angles required by the standard, does not need human participation and operation after starting, and is simple and quick to test.
