Product Description
I. Overview
This product employs fluorescent UV lamps that closely replicate the UV spectrum of natural sunlight, combined with temperature‑control and humidity‑supply systems to simulate the environmental factors—such as high temperature, high humidity, condensation, and alternating wet/dry cycles—that cause material degradation, including discoloration, loss of brightness and strength, cracking, flaking, chalking, and oxidation. By leveraging the synergistic effects of UV radiation and moisture, the equipment effectively degrades a material’s resistance to light or moisture, rendering it ineffective. Consequently, it is widely used for evaluating the climatic durability of materials. The device offers superior UV‑light simulation, low operating and maintenance costs, and ease of use; it features automated control, a highly automated test cycle, excellent lamp stability, and outstanding reproducibility of test results.
