Rainy Night Retroreflector meter for Road Markings
Features:
1. High values are more accurate and will not be interfered with by external light.
2. One-click printing on-site (no need for an additional printer)
BASIC INFO
The rainy night retroreflector meter for road marking is a portable on-site measurement instrument with an open light path, used to measure the retroreflection brightness coefficient of the marking line. Unit: mcd·m-2·lx-1. The main characteristics of its research are: simulating a motor vehicle driving on the road at night, the headlights shining on the markings (made of retroreflective material) on the road, and the brightness observed by the driver in the cab after reflection. The parameter measured is the nighttime retroreflective luminance coefficient, or RL value.
Specifications:
Measurement Capabilities: It measures retroreflection coefficient in the range of 0-4000 mcd.m⁻²lx⁻¹ with an observation angle of 1.05° and an incident angle of 88.76° (complementary angle 1.24°).
Performance Metrics: The device has a repeatability measurement error of ≤3% and a light source colour temperature of 2856±50K.
Power and Storage: It offers a battery continuous working time of >72h, a built-in battery capacity of 13Ah, and 16GB of data storage space. The charging power supply is DC 8.4V.
Environmental and Physical Specifications: It operates within an environment temperature range of -15°C to +60°C with ambient humidity <98% (no frost). The overall machine volume is 380mm x 134mm x 170mm.
