BN-UV3 UV aging test chamber have been developed to provide a UV weathering. The UV simulates the effect of sunlight with fluorescent ultraviolet (UV) lamps, while rain and dew are simulated by the condensation of humidity, dark rain cycle and other factors, and through the synergy between UV and moisture make the material a single light-resistant ability or single weakened wet ability or failure, which is widely used in materials Weathering performance evaluation, the device has to provide the best UV simulation of the sun, the use of low maintenance costs, easy to use, automatic control of equipment used, the test cycle of a high degree of automation, light stability, high test results reproducibility.
