Function:
This product uses a fluorescent UV lamp that can best simulate the UV spectrum in sunlight and combines with temperature control, humidity supply and other devices to simulate discoloration, brightness and intensity reduction of materials; cracking, peeling, pulverization, oxidation and other factors such as sunlight (UV band), high temperature, high humidity, condensation, dark cycle, etc. At the same time, through the synergistic effect between UV light and moisture, the single light resistance or single moisture resistance of materials is weakened or invalidated, which is widely used to evaluate the weather resistance of materials.
