testermeter-RM66 Retro-Reflection Meter，Reflectometer for sign board test,road marking measurement
Overview
| The reflection meter is a specialized instrument used to measure the anti reflection coefficient of vehicle reflective materials, various levels of highway traffic sign boards and clothing, as well as various marking reflective strips. It can also be used by reflective material manufacturers and distributors to test and control product quality, and by quality supervision and law enforcement departments to test related reflective materials. |
Testing principle
| Measurement of reflective materials, expressed internationally as the commonly used retroreflection coefficient, unit: cd/lx/m²， Its physical meaning is: under certain geometric conditions, the brightness value generated per unit area of reflective material under unit illumination. |
