TBTRMR-2J road marking retroreflectometer is an open-optical-path designed small size portable on-site measuring instrument, the weight is 3.5kg.

Main use is to measure the in-night brightness of road marking made of retroreflective material simulating under illumination from the headlights of vehicles driving on road, i.e, the in-night brightness observed by the driver in vehicle. The measured parameter is the nighttime retroreflective brightness coefficient, namely RL value.

This instrument test result accurate and repeatable, simple to operate, can be used in laboratory or field.
