Dry and wet state reverse reflection coefficient tester
Product Information:
Dry and wet state reverse reflection coefficient tester is used to simulate the evaluation of the reflective performance of occupational high-visibility warning materials in dry state and wet state, and to determine the reverse reflection coefficient of the sample surface. It is suitable for visible warning clothing worn by various posts to ensure the safety warning of personnel.
