UV Aging Test Chamber
UV aging test chamber is suitable for quality inspection and material screening of electronics, electrical appliances, communication, instruments, vehicles, plastic products, metals, building materials, and aerospace to name a few. This test chamber adopts fluorescent ultraviolet lamps with optimal UV spectrum simulation in sunlight, temperature control, humidity control and other devices to simulate sunlight that causes discoloration, brightness, decrease in intensity, cracking, peeling, powdering and oxidation, high temperature, high humidity, condensation, or dark rain cycle while diminishing the light resistance or moisture resistance of tested material through the synergy between UV light and moisture. It is therefore widely used to evaluate the weather resistance of materials.
