Multi-angle Retroreflectometer overview

MAR-932 multi-angle Retroreflectometer is a portable testing equipment that is professionally used to measure the retroreflective optical characteristics of various reflective safety materials. It is widely used in various road traffic reflective products, vehicle safety reflective products, and safety production signs, On-site inspection and inspection of reflective cloth, etc.

Standards:

Meet the following standards: (The angle can be adjusted according to specific standards)
1. The American standard ASTM E1709-08 uses the 0.2 observation angle retroreflectometer to measure the test method of retroreflective marks
2. The American standard ASTM E2540 uses the 0.5 observation angle retroreflectometer to measure the test method of retroreflective marks
3. High-brightness reflective clothing test under EN 471 and ANSI 107 standards.
4. European standard EN 12899-1-2007 requirements for vertical fixed traffic signs:
5. American ASTM D4956-2016 Standard Specification of Reflectors for Traffic Control
6. German DIN67520
