LA-931 Multi-angle sign retroreflection coefficient measuring instrument

LA-931 multi-angle sign retroreflection coefficient detector is a new type of portable
road traffic safety testing equipment. It adopts the standard transfer indirect
measurement method. It is professionally used to measure the retroreflective optical
characteristics of various reflective safety signs and is suitable for road traffic On-site
inspection and inspection of reflective products, vehicle safety reflective products,
safety production signs, etc.
