Air-Cooled Xenon Lamp Aging Tester

The Air-Cooled Xenon Lamp Aging Tester is a laboratory instrument designed to simulate natural sunlight exposure, enabling accelerated testing of materials, coatings, plastics, paints, and other products for UV degradation, color fading, cracking, chalking, and other aging effects. This device is widely used across automotive, aerospace, coatings, plastics, textiles, and electronics industries.

1. What is an Air-Cooled Xenon Lamp Aging Tester?

An Air-Cooled Xenon Lamp Aging Tester uses a xenon arc lamp as a full-spectrum light source to replicate sunlight, including UV, visible, and infrared light. Unlike water-cooled xenon testers, it uses air-cooling to maintain lamp temperature, which simplifies installation and reduces maintenance while ensuring consistent irradiation.

Key components include:

High-intensity xenon lamp with full-spectrum output

Air-cooling system with fans and airflow management

Test chamber with sample holders and temperature/humidity control

Electronic timer, irradiation controller, and intensity monitoring

Optional accessories for moisture/fog simulation

The system accelerates the aging process, allowing manufacturers to predict long-term material durability in months instead of years.
