Multi-angle Retroreflectometer for Traffic Signs
Introduction
TBTTSR-1M retroreflectometer is an instrument for measuring RA (nighttime retroreflection) on traffic sign, high visibility clothing, conspicuity tape and license plate.
The advanced optical system can measure up to 4 (four) simultaneous observation angles.
The basic illumination angle (β) can be −4° or 5°, can change different illumination angle via angle adapter and combine with the observation angles simultaneously, thus allows precise determination of retroreflection according to international standards.
