LFY-224E Dry and Wet State Retroreflective Coefficient Tester
This instrument is used to simulate the evaluation of the reflective performance of occupational high-visibility warning materials in the dry state and the rain-wet state, and to determine the retroreflective coefficient of the sample surface. It is suitable for the visibility warning clothing worn by various positions. Ensure personnel safety warnings.
