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.

Road marking’s visibility, the retroreflectivity is correlated with roadway safety, it directly presented as the night visibility (RL) of pavement markings. The TBTRMR-VM vehicle-mounted marking retroreflectometer allows a constant and efficient assessment of the state of road markings while maintaining traffic flow. The detection accuracy is consistent with the handheld retroreflective readings.
The major components of the system are the host, computer processing system, and DMI (distance measuring wheel). The host is consist of optical measurement system, control system, imaging driver assistance system, height / tilt compensation system and Beidou positioning antenna.

TBTTSR-1 retroreflectometer is designed for retroreflectivity measurements of retroreflective materials, including road traffic signs, high-visibility clothing, licence plates and reflective tapes.
TBTTSR-1M is a portable multi-angle detector for measuring night visible photometric properties (coefficient of retroreflection RA and R’) of retroreflective materials on spot. It is a convenient instrument used to test traffic signs for highway, railway, aviation or reflective markings on trucks, to ensure retroreflective markings meet the requirements of relevant standards.
The instrument is designed conforming to China's national standard GB / T 18833-2012, GB / T 26377-2010-2012 , GB / T 21861-2014 and JJG 059-2004".
