Reliable LED UV Aging Test Chamber For Precise Lab UV Accelerated Weathering Tests
Product Description:
The UV Weathering Test Chamber is equipped with a fluorescent UVA/UVB lamp. This lamp accurately mimics the UV spectrum of sunlight, enabling the simulation of natural sunlight conditions.
Within the chamber, materials are subjected to precisely controlled, alternating cycles of UV light exposure and moisture, all while maintaining elevated temperatures. This environment closely replicates real - world weathering scenarios.
The chamber is an invaluable tool for testing various types of material damages. These include color change, where the material's original hue is altered; gloss loss, resulting in a reduction of its shiny appearance; chalking, which causes a powdery residue on the surface; cracking, creating fissures in the material; crazing, forming a network of fine cracks; hazing, leading to a loss of transparency; blistering, with the appearance of small bubbles on the surface; strength loss, weakening the material's structural integrity; and oxidation, where the material reacts with oxygen and deteriorates.

FAQ:
1.Besides the common material aging tests, can the equipment simulate the intermittent lighting conditions in actual use scenarios?
Absolutely. Through the intelligent control system of the equipment, you can freely set the on - off time of the lighting and the light intensity change curve, accurately simulating the intermittent lighting in actual use scenarios. For example, it can simulate the lighting conditions of outdoor lamps during day - night alternation, or the state of indoor products being irradiated by sunlight at different times, meeting diverse testing needs.
2. If the equipment runs continuously for a long time, how is the stability of its temperature, humidity, and light intensity ensured?
The test chamber uses high - quality components for temperature control, humidity control, and lighting systems, which have excellent stability. The intelligent control system will monitor the temperature, humidity, and light intensity in real - time. Once any deviation occurs, it will automatically adjust immediately. Moreover, the equipment has a built - in redundant backup mechanism. Key components such as sensors and controllers have backup modules to ensure that during long - term operation, all parameters remain stable, providing a reliable environment for your tests.
3. I hope to monitor some physical property changes of the samples during the test. Can the equipment integrate other monitoring instruments?
Our test chamber has reserved various interfaces for easy integration of various monitoring instruments, such as infrared thermal imagers and tensile testers. Through customized development, these instruments can be integrated with the control system of the test chamber to achieve simultaneous monitoring and data collection. You can view both the ultraviolet aging data and the physical property changes of the samples on the equipment operation interface, improving the test efficiency and comprehensiveness.
4. If I have special requirements for the internal layout and size of the equipment, can it be customized?
We provide customization services. Whether you need to expand the internal space of the test chamber to accommodate large - sized samples, adjust the equipment's outer dimensions according to the laboratory layout, or have special requirements for the internal structure of the sample racks, our technical team can conduct targeted design and production according to your requirements to ensure that the equipment fully meets your usage scenarios.
