Name：Marking retroreflective coefficient measuring instrument
Model：BX-II
Specification
Implementation standard of retroreflective marking measuring instrument:
The retroreflective marking measuring instrument is a special instrument for measuring the optical performance of the retroreflective marking.
National standard GB/T16311-2004 “Quality Requirements and Testing Methods for Road Traffic Markings”,
The transportation industry standard JT/T280-2004 “Pavement Marking Coatings” all stipulate technical indicators for the optical performance of the night visibility of the reflective markings. The retroreflective marking measuring instrument provides a measuring instrument for controlling the construction quality.
Description of retroreflective marking measuring instrument:
The brightness of the inverted cursor line is expressed by the retroreflective coefficient in the world, and the unit is mcd/lx/m2. Its physical meaning is: the brightness value produced on a unit area under a unit illumination condition. Place the instrument on the marking line to be measured, the instrument displays the retroreflective coefficient value in digital form, which reflects the driver’s objective evaluation of the reflective brightness of the marking line under driving conditions. The instrument consists of a measuring host, a power supply, a charger, and a standard board.
