The Solar Simulation Weathering Test Chambers are state-of-the-art test units for simulating temperature and climatic indoor and outdoor conditions with global irradiation. Our solar simulation chambers simulate direct sunlight, heat, cold and humidity in order to test the many small and large items of day-to-day life that are subjected to different levels of solar radiation. These environments affect the service and operating conditions of various products exposed to these environmental extremes. They cause colors to fade and accelerate the ageing of materials. For many products, a light resistance test, also combined with other environmental factors, is indispensable.
