ASTM D4799 UV Accelerated Weathering Tester Environmental Test Chamber
PID SSR Control UV Aging Test Chamber / Ultraviolet UVA Light Tester
Overview:
A fluorescent ultraviolet lamp similar to that of the UV spectrum in the sunlight, combined with a temperature control device, is used to analogize the material to cause discoloration, brightness, strength decline, cracking, spalling, powdering, oxidation, etc. The sun (UV segment) is damaged by high temperature, high humidity, and condensation. Factors such as dark rain cycle and so on, at the same time, through the synergistic action between ultraviolet light and moisture, the single light resistance or single moisture resistance of the material is weakened or invalidated, so it is widely used to evaluate the climate resistance of the material. The equipment has the best sunlight UV simulation, low maintenance cost, easy to use, automatic operation of the equipment, high degree of automation of the test cycle, lighting The stability is good and the re-occurrence rate of the test results is high.
