TBTTSR-1M retroreflectometer is an instrument for measuring RA (nighttime retroreflection) on high visibility clothing, traffic sign, conspicuity tape and license plate.
The advanced optical system can measure up to 5 (five) simultaneous observation angles.
The basic illumination angle (β) can be 5° or −4°, 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.
EN ISO 20471 (High visibility clothing - Test methods and requirements), ASTM E1709, ASTM E2540, ASTM E1809, EN 12899, GOST 52290, GOST 32945, GOST 50577
