Used for testing the aging resistance of textiles, leather, plastics, rubber and other materials exposed to ultraviolet light. The equipment is irradiated by the original imported UVA-340 fluorescent UV lamp. At the same time, it can simulate the influence of moisture by condensation or spraying, which is used to evaluate the changes in the fading, color change, luster, crack, foaming, embrittlement, oxidation and other aspects of the material.
