Rainynight marking line retroreflection detector

The marking line retroreflection measuring instrument is a portable on-site measurement instrument with an open light path, used to measure the retroreflection brightness coefficient of the marking line. Unit: mcd·m-2·lx-1. The main characteristics of its research are: simulating a motor vehicle driving on the road at night, the headlights shining on the markings (made of retroreflective material) on the road, and the brightness observed by the driver in the cab after reflection. The parameter measured is the nighttime retroreflective luminance coefficient, or RL value. This instrument can measure the marking line and the retroreflection brightness coefficient of the oscillating marking line under three conditions: dry R_L, wet R_(L_wet) and continuous rainfall R_(L_rain).

This instrument complies with the following standards:

GB/T 26377-2010 “Retroreflection Measuring Instrument”,

GB/T16311-2009 “Road Traffic Marking Quality Requirements and Testing Methods”,

JJF 1809-2020 “Calibration Specifications for Retroreflection Measuring Instruments”

JTGF80-1-2017 “Highway Engineering Quality Inspection and Assessment Standards”,

DB36/T978-2017 “Quality Requirements and Testing Methods for Reflective Markings on Road Traffic on Rainy Nights”,

DB51/T2429-2017 “Quality Requirements and Testing Methods for Reflective Markings on Highway Traffic on Rainy Nights” and other standard requirements.

ASTM E1696-2015 , EN 1463

High values are more accurate and will not be interfered by external light. One-click printing on-site (no need for additional printer)
