Accelerated Weathering Aging Machine UV Test Chamber

Accelerated Weathering Aging Machine UV Test Chamber

Uv Weathering Test Machine is the world's most widely used ,can be used in more labs throughout the world than any other accelerated weathering tester. It's used widely in the industry, such as printing ink, paint, pastics, print, packaging,motor van, metal, electron, medical, and so on.

Uv Weathering Test Machine ,simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering - ultraviolet radiation, moisture and heat. A UV accelerated weathering chamber uses fluorecent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters.
