AT-RS-001Retroreflectometer For Road markings (Raised road signs)
The raised pavement markers Retroreflectometer is a portable, on-site measuring instrument used to measure the luminous intensity coefficient of Raised Pavement Markers. The instrument simulates the luminous intensity produced by a motor vehicle's headlights illuminating a raised road sign during nighttime driving.The measured parameter is the luminous intensity coefficient ,namely R value.
The raised pavement markers Retroreflectometer adopts an optoelectronic iintegration with high precision, high stability and open light source structure design.The system applies high-standard MCU master module, large-capacity storage unit, touch screen display with keyboard pinyin input functionand embedded program control software, supports for rapid inspection and prints out results on site through the built-in printer. It is featured by free preheating, small measurement error, out-of-the-box and so on. This is a necessary instrument for the production, quality supervision, engineering construction, supervision and other units to measure the retroreflection performance of road marking.
Main Functional Characteristics
- Supportsrapid measurement(measuring coefficient of luminous intensityvalue within3seconds);
- Open optical path, free from external light interference during measurement;
