Accelerated uv testing equipment is named "ultraviolet weathering test box". It uses fluorescent ultraviolet lamp as the light source, simulates ultraviolet radiation and condensation in natural sunlight, and conducts accelerated weathering test on the material to obtain the result of weathering resistance of the material.Uv, drenching, high temperature, high humidity, condensation, dark and other environmental conditions in the natural climate can be simulated. By reproducing these conditions, a cycle can be merged and the cycle times can be completed automatically.

Uva-340 lamp: uva-340 lamp can perfectly simulate the short-wave ultraviolet light in sunlight, that is, the wavelength range from 365nm to 295nm at the cut-off point of sunlight.
Uvb-313 lamp tube: uvb-313 lamp occurs in the short-wave ultraviolet light than the usual exposure to the earth's surface of the sun's uv intense, which can maximize the acceleration of material aging.However, some materials may be damaged by uv aging lamp.Uvb-313 lamp is mainly used for quality control and research and development, or for testing materials with strong weather resistance.
