Portable Road Sign Multi-Angle Reflectometer

NJTT- 101E portable road sign multi-angle reflectometer is an instrument for measuring the reflection coefficient of intelligent traffic signs .It can be used for laboratory and field measurement of the retro-reflectivity coefficient of traffic sign (reflective film) materials, vehicle reflective stickers and other materials. It is suitable for quality supervision departments, engineering construction and supervision units to control and inspect the quality of sign retro-reflectivity coefficient; traffic management departments and vehicle inspection stations to measure the reflective performance of truck-type motor vehicle body reflective identification; and the production enterprises of retro-reflective materials to monitor the quality of their produced reflective materials.
