This series of machine adopts the best simulation of sunshine UV spectral fluoresvent UV lamp and combines with control temperature and supply humidity device to imitate the color change, luminance and strength reduction for material; cracking, spalling, pulverization, oxidation and other damaged sunshine (UV section) high temperature, high humidity, condensation and dark period factors, together with UV-light and humid sybergistic effect to the single light fastness or single moisture-proof decreased or lose efficacy for the material. Thus widely used to evaluate the performance of the climate resistance of materials. |
