With the Xenotest 220/440 instruments, material changes caused by weathering - sunlight, temperature and moisture, can be highly accelerated. For example, color fading, embrittlement or yellowing that would occur naturally over the course of months or years can be realistically simulated within days or weeks. The Xenotest 440 model is a highly versatile weathering instrument suitable for testing materials such as textiles, plastics, coatings as well as interior and exterior automotive parts. The Xenotest 440, with XenoLogicTM lamp technology, is powered by two 2200 W xenon lamps capable of reaching 2-sun irradiance levels for significantly shorter test times and longer lamp service life.
