Pavement Marking Retroreflectometer | Marking Line Reticle Retroreflective Tester

The LS-101A/LS-101C Pavement Marking Retroreflectometer | Marking Line Reticle Retroreflective Tester is a precise handheld photoelectric instrument designed for on-site measurement of photometric properties, specifically the retroreflection coefficient (R’) of retroreflective materials. It is tailored for quality inspection of traffic sign materials, suitable for material manufacturers, quality supervision departments, engineering construction and supervision units, and meets the testing needs of traffic safety management and highway, railway, and aviation departments for retroreflective signs. Additionally, it assesses the reflective performance of markings on truck bodies. The instrument comprises an optical system, a detection and amplification system, a power supply and control system, a display system, and a calibration block. A dedicated calibration block is included for calibration. The instrument features an LCD digital display for measured values and is powered by a lithium battery, ensuring accurate and reliable measurement results and ease of use.
