UV-A / UV-B Chamber Type Accelerated Weathering Test Chamber
This advanced weathering test chamber simulates the damaging effects of sunlight, rain, and dew on materials. Using fluorescent UV lamps to replicate sunlight and condensation to mimic rain and dew, it subjects test materials to alternating light and moisture cycles at controlled temperatures. The chamber reproduces outdoor weathering hazards in just days or months, helping evaluate material durability and performance.
Applications
Ideal for testing coatings, inks, paints, resins, plastics, rubber, printing and packaging materials, aluminum profiles, adhesives, automotive components, cosmetics, metals, electronics, electroplating, and pharmaceutical products.
