Fabric UV resistance tester

The Fabric UV Resistance Tester is designed to simulate solar UV radiation and evaluate the ultraviolet protection performance of textiles, sun-protection products, and cosmetics. The instrument replaces in-vivo testing, providing accurate SPF measurement, UVA/UVB analysis, and critical wavelength evaluation. It combines a stable UV-visible light source, spectrophotometric detection, and powerful data analysis software, offering fast, economical, and reproducible testing.

Application

Assessing SPF value, UVA/UVB absorption, and UV protection of fabrics, sunscreens, and cosmetics.

Research & development of UV protective clothing and sun-care products.

Quality control in textile manufacturing, cosmetics production, and certification labs.

Replaces human body (In-Vivo) testing for cost-effective and standardized UV evaluation.
