The GT-3000 Water-cooled Light Fastness Tester is a professional-grade Weatherometer designed to simulate the most extreme outdoor conditions. this xenon weathering test chamber provides accurate simulation of full-spectrum sunlight, humidity, and rain. It is the ideal solution for industries requiring high-irradiance testing, such as automotive, coatings, and plastics. Fully compliant with ASTM G155 and ISO 105 B02 standards, the GT-3000 ensures your materials meet the most rigorous global durability requirements.

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.

The Intelligent UV Weathering Chamber GT-C29D simulates sunlight, moisture, and temperature to evaluate long-term outdoor degradation—such as color fading, cracking, embrittlement, and oxidation—in just days or weeks. Equipped with UVA-340 or UVB-313 fluorescent lamps, automatic water spray/condensation, and a smart PLC touchscreen with closed-loop irradiance control, it ensures highly repeatable testing for plastics, textiles, coatings, rubber, and automotive components.  As an original physical testing machine manufacturer, GESTER supplies factory-direct uv chamber fully compliant with ISO 4892, ASTM G154, and ASTM D4329.
