Product Details

Product description

Programmable auto UVA lamp accelerated aging test chamber is applicable for the sunlight resistant test of nonmetallic materials and aging test of artificial light sources. A variety of industrial products can make the reliability test, and this product can simulate the product in the sun, rain, humidity and dew conditions, including damage caused by bleaching, color, brightness down, powder, crack, blur, brittle, intensity decreased and oxidation.

Applications

Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature.
To get the results of damage after several days or weeks which is equal to expose to outside for a few months. The damages include fading, discoloration, brightness down, powder, crack, blur, brittle, strength decreases and oxidation.
Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.
