Support To Set The Line Color Measurement, Optional White, Yellow,
Red, Green Of Retroreflectometer For Road Markings
Product introduction
STP-NRRM marking retroreflectometer is a portable on-site measuring
instrument, used for measuring the retroreflection characteristic
of road marking. STP-NRRM instrument is to simulate the brightness
of road marking that can be seen by the driver under the
illumination of motor vehicles at night, and the measured parameter
is the coefficient of retrorefection brightness at night, namely, RL value.
The angle between the optical axis of the headlamp and the normal
line (reference axis) of the road surface is called the incidence
angle, which is set at 88.76° and the angle between the optical
axis of the headlamp and the reflected light is called the
observation angle, which is set at 1.05°. The light source of the
optical system is directed to the marking line according to the
incident angle. The size of measurement window is 450 x 65mm. The
reflected light from the marking line is received by the V(λ)
filter at the observation angle of 1.05°. After signal processing
and calculation, the measured value is displayed. This value is the
value of retroreflection coefficient RL.
