AT-MAR-003 Sign reflective measuring instrument is a new type of portable traffic safety detection equipment, which is used to measure the reflective optical characteristics of various reflective safety signs, and can be used for on-site detection of traffic reflective products and vehicle safety reflective products.

The Retroreflectance measuring instrument is a portable field measuring instrument, which can simulate the road marking brightness visible to the driver under the headlamp illumination of motor vehicle at night. The measured parameter is the luminous Retroreflectance coefficient at night, i.e. R_L  Qd value, in mcd·m^-2·lx^-1. It is used to measure the retroreflection characteristics of road markings. It is suitable for laboratory environment and field measurement. Road marking manufacturers, road marking process construction units and road quality supervision units are used to measure the retroreflective performance of road markings.

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).
