Unit: mcd\u00b7m-2\u00b7lx-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). Specifications: Measurement item: Retroreflection coefficient mcd.m-2.lx-1 Measurement value range: 0&#8212;4000 Observation angle: 1.05\u00b0 Incident angle: 88.76\u00b0, complementary angle is 1.24\u00b0 Light source color temperature: 2856\u00b150K Measurement area: 250mm x 75mm Repeatability measurement error: \u22643% Battery continuous working time: &gt;72h Data storage space: 16GB Built-in battery capacity: 13Ah ..."}
