Function:
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 factors such as sunlight (UV segment) high temperature, high humidity, condensation, dark cycle, etc. that cause discoloration, brightness, strength decline: cracking, peeling, powdering, oxidation and other damages to materials. At the same time, through the synergistic effect between ultraviolet light and moisture, 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.
