Ci 35/65 Weather Ometer


In the natural environment, light, moisture and heat combine synergistically to cause photochemical and mechanical changes to your product. Predicting these changes in the laboratory depends on close simulation of the actual end use conditions. The Atlas Ci65A reproduces and accelerates the degradation process in a controlled exposure test with precision and repeatability.

The Ci65A provides radiant energy using a single water cooled xenon arc lamp whose filtered output closely simulates natural sunlight.

Temperature can be continuously monitored and controlled throughout the test. The Ci65A can produce three different types of moisure – humidity, condensation and direct water spray. The Ci65A can be programmed to cycle your exposure test between light and dark cycles plus sample wetting.

The Ci35F fade-ometer is specifically designed for fade/lightfastness testing , including textile/geotextile materials subjected direct sunload exposure or by filtered window glass exposure.
