This product uses fluorescent ultraviolet lamps that can best simulate the UV spectrum of sunlight and combines temperature control, humidity supply, and other devices to simulate the damage of sunlight (UV band), high temperature, high humidity, condensation, dark cycle, and other factors that cause discoloration, brightness, strength decline, cracking, peeling, powdering, oxidation and other damage to materials. At the same time, through the synergistic effect between ultraviolet light and humidity, the single light resistance or single moisture resistance of the material is weakened or invalidated, so it is widely used to evaluate the weather resistance of materials.
