This high-performance accelerated weathering tester simulates the devastating long-term effects of natural sunlight, rain, and dew on textiles, plastics, coatings, and automotive parts within days or weeks. Utilizing premium UVA-340 or UVB-313 fluorescent lamps alongside automated water spray and condensation cycles, it accurately reproduces material degradation such as color fading, cracking, chalking, oxidation, and embrittlement.  Built with a heavy-duty SUS304 stainless steel cabinet, a precise PLC touch screen, and a smart closed-loop irradiance control system, the UV weathering test chamber GT-C29 delivers unmatched repeatability and strict compliance with global standards like ASTM G154, ISO 4892-3, and ASTM D4329.
