The xenon weathering test chamber is designed to simulate the destructive effects of natural sunlight, including ultraviolet radiation, visible light and thermal stress, and combines controllable humidity and rainfall to accelerate material aging. It assesses the weather resistance of plastics, coatings, rubber, automotive parts, textiles and photovoltaic materials to ensure the durability of products in outdoor environments.
Key features
Xenon Weathering Test Chamber

Product details
Xenon Weathering Test Chamber
Rotating sample holder
The rotating sample holders are not only aesthetically pleasing but also stable and easy to install as they can be inserted by simply aligning test pieces.The illustration shows a batch test of leather

Black panel
A black standard thermometer BPT with wide temperature control range,which can reach up to 85℃. There are temperature sensors that provide real-time feedback and intelligently adjust the temperature, reducing temperature fluctuations.

Spray nozzles
Cooling high-power xenon lamps to control water temperature to avoid overheating; Use humidifying or spraying device to adjust the humidity inside the chamber and simulate rainfall; Supporting water tank, stainless steel pump, filter system to form a closed loop cycle.

Radiometer
The xenon accelerated weathering tester is equipped with an internal irradiance sensor (optional bands include 340 nm, 420 nm, 300-400 nm) to monitor the light intensity in real time. Automatic closed-loop control of light intensity.
