The LIB xenon weatherometer simulates natural weathering conditions, including sunlight (xenon arc radiation), temperature, humidity and rainfall. It assesses the durability of materials such as plastics, coatings, textiles, automotive parts and packaging under accelerated aging, helping manufacturers identify color fading, surface degradation or changes in mechanical properties.
Key features
Xenon Weatherometer
Complete solar spectrum (UV+ visible light + infrared), closest to natural sunlight
Integrate multiple environmental variables such as light, temperature, humidity and water spray circulation
The light intensity is controllable.Typical control points 340nm: 0.35-1.10 W/m²
In combination with the blackboard temperature sensor, it achieves long-term test stability
Built-in pure water filtration system and an automatic water spraying function, which can simulate the scouring of rainwater
Continuous light (dry) and alternating light + rain (wet) testing to simulate real climate
Color touch screen, supporting program editing, real-time data viewing, and data export

Product details
Xenon Weatherometer
Water-cooled xenon lamp
Water-cooled xenon arc lamps fulfill the environmental concept of water conservation due to the powerful automated water circulation system.

Light filters
Light filters ensure the reliability of the data due to the strong stabilization of light, avoiding interference with stray light and improving the accuracy of the test.

Spray nozzle
Stainless steel nozzles are distributed on each layer of the sample holder to simulate real rain and condensation,to simulate natural wet and dry cycles.

PC link
Multilingual interface ensures global availability. USB and cloud storage test report (PDF/Excel), including irradiance, temperature, humidity curves. The controller has automatic error detection and audible alarm.


LIB provides you with tailor-made xenon weatherometer for your material testing needs. LIB offers end-to-end services, from device selection to compliance certification, to ensure that your products can withstand the weathering of the real world.
