Home » Rainy Night Retroreflectometer For Road Markings LT-SRMR-R
The rainy - night retroreflectometer is a portable on - site measurement instrument with an open light path, which is used to measure the retroreflection brightness coefficient of the marking line. Unit: mcd·m⁻²·lx⁻¹. This instrument can measure the retroreflection brightness coefficient of the marking line and the oscillating marking line under three conditions: dry R_L, wet R_(L_wet) and continuous rainfall R_(L_rain).
When measuring the retroreflection coefficient under humid conditions and continuous rainfall conditions, it should be used with a professional rainfall simulation device.
