Performance

LTL3500 measures all types of road markings at a simulated distance of 30 m with high accuracy. The instrument operates with a reproducibility of +/- 5 % and a repeatability of +/- 2 %. The LTL3500 has a RL profile capacity of 15 mm.

Measurement of color coordinates (x,y)

LTL3500 measures nighttime retroreflected color – CIE chromaticity – for white and yellow markings according to EN1436 and ASTM D6628. Measuring color coordinates tells for example if yellow markings are seen as yellow at night as intended or they are viewed as white. .
