Accelerated UV Weathering Tester – High-Intensity Metal Halide Lamp | SUV-W171
Accelerate Years of UV Exposure into Days – Precision, Power, and Lower Lifetime Costs
The IWASAKI EYE Super UV Tester SUV-W171 is a next-generation accelerated weathering tester designed for maximum performance and long-term value.
Powered by a 6kW water-cooled metal halide lamp, it delivers more than 30 times the UV intensity of standard weather meters—compressing years of outdoor exposure into days.
Engineered for reliability, versatility, and efficiency, the SUV-W171 helps R&D and QA teams validate product durability, meet ASTM and ISO requirements,
and reduce total cost of ownership through lower energy use and extended component life.
Why Choose the SUV-W171?
⌛Ultra-Fast Testing Cycles
Achieve up to 150 mW/cm² UV intensity—simulating years of outdoor conditions in days or weeks.
🌎International Standards Alignment
Meets or exceeds ASTM and ISO UV weathering test requirements for globally recognized, repeatable results.
💰Lower Lifetime Costs
Durable components, extended lamp life, and 20% lower energy consumption compared to previous models reduce operating costs over time.
🌞Versatile Environmental Simulation
Supports UV irradiation, condensation, darkness, and shower cycles—all in a single, compact chamber.
✅Optimized for R&D and QA
Ideal for rapid material screening, product development, and reliability verification before market release.
☆30 times or greater UV irradiation intensity than conventional wheathermeters. Unprecedented test speeds.
