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. We offer custom specimen holders, worldwide shipping, and long-term technical support. Contact us today for a quote or technical datasheet.
