Xenon test chamber is an accelerated weathering tester by simulating true environmental conditions. It utilizes xenon arc lamp capable of simulating the full sunlight spectrum to replicate destructive light waves present in different environments. Using a long arc xenon lamp as the light source, it is designed to simulate and intensify weathering and accelerated aging tests, enabling rapid acquisition of near-atmospheric aging test results. By precisely controlling test conditions, this test chamber can simulate various climate conditions in the laboratory and perform repeated tests to validate the reliability of the results, making the xenon test chamber an effective tool for evaluating the weather resistance performance of materials.
