Hand-held Retroreflectometer for Road Marking Test

Retroreflective marking measuring instrument is a special optical measuring equipment used to measure the reflective performance of road marking. The measured parameter is the retroreflective coefficient rl ‘(or specific brightness) of marking, and the unit is MCD • m-2 • LX – 1. The instrument has the advantages of simple operation and reliable measurement value. It can be used in both laboratory and field measurement. It is the first choice for production, quality supervision, engineering construction, supervision, teaching and scientific research units to measure the retroreflective optical performance of highway markings.
