Road Pavement Protruding Signs Mark Retroreflectometer

The LS-201C Road Pavement Protruding Signs Mark Retroreflectometer is a precision instrument engineered to measure the coefficient of luminous intensity, the primary photometric performance parameter for raised pavement markers. This device operates on a Windows CE-based control platform, incorporating a 32-bit high-speed ARM processor core operating at 500MHz, which delivers robust computational performance for accurate data acquisition and processing. The system features a comprehensive embedded architecture with 64MB SDRAM system memory, ensuring reliable operation in demanding field and laboratory environments.

The instrument is specifically designed for compliance testing according to international standards including ASTM E1696 “Standard Test Method for Field Measurement of Raised Retroreflective Pavement Markers Using a Portable Retroreflectometer,” ASTM D4280 “Standard Specification for Extended Life Type, Nonplowable, Raised Retroreflective Pavement Markers,” DIN 67520:2013-10 “Retro-reflecting materials for traffic safety – Photometric minimum requirements for retro-reflective sheetings,” and BS/EN 1463 “Road marking materials – Retroreflecting road studs.”

Application domains include:

• Photometric laboratories and accredited testing centers conducting standardized compliance verification
• Highway construction and maintenance sites for field measurement of installed pavement markers
• Manufacturing facilities performing quality control inspections on raised pavement marker production
• Retroreflective material manufacturers monitoring material performance and consistency
• Transportation departments and regulatory bodies conducting pavement safety assessments

The device is optimized for rectangular road pavement protruding signs mark configurations, with measurement parameters calibrated to standard geometric observation and illumination conditions. The human-machine interface incorporates an LED-backlit high-definition true-color digital display with 320×240 resolution, providing real-time measurement data visualization. System functionality includes parameter calibration routines, automatic zero adjustment algorithms, and configurable preset parameters for detection time, geographic location, and system information management.
