Fluorescent UV Test Chamber is a specialized testing equipment designed to simulate the aging process of materials under ultraviolet radiation. It primarily utilizes fluorescent UV lamps to replicate the ultraviolet component of sunlight. The fluorescent substances within these lamps emit ultraviolet radiation at specific wavelengths when electrically energized.
