Environmental Test Chamber compliant Xenon Weathering Aging Test
chambers
Applications:
A UV accelerated weathering test chamber functions by imitating the
harmful impacts that long - term outdoor
exposure has on materials and coatings. It does this by subjecting
test samples to diverse conditions of the most corrosive
elements in weathering, namely ultraviolet radiation, humidity, and
heat. This type of chamber utilizes fluorescent lamps to
generate a radiation spectrum that is concentrated in the
ultraviolet wavelengths. Moisture is introduced through forced
condensation, while the temperature is regulated by heaters.
