UV Weathering Tester Z-UV

UV Weathering Tester Z-UV

UV Weathering Tester Z-UV

This product utilizes eight Atlas UV fluorescent lamps, combined with temperature control and humidity supply systems, to simulate sunlight (UV spectrum), rain, and dew that cause material degradation such as discoloration, loss of brightness and strength, cracking, peeling, chalking, and oxidation. By reproducing the synergistic effects of ultraviolet light and moisture, the tester accelerates the failure of materials with limited resistance to light or humidity alone. It offers excellent test repeatability and is suitable for evaluating the effects of UV, temperature, and humidity on a wide range of materials, including coatings, plastics, pigments, adhesives, and fabrics.

The Z-UV UV Weathering Tester simulates the effects of ultraviolet radiation, moisture, and temperature to accelerate material degradation. It helps manufacturers evaluate weathering performance and failure risks under outdoor-like conditions. Ideal for testing coatings, plastics, rubber, textiles, and other industrial materials.
