Advantages

1. High-Fidelity UV Simulation: Equipped with 8 U.S.-made UV lamps (UVA-340, UVB-313, UVB-351), the chamber delivers precise and stable UV irradiance with minimal spectral deviation. This ensures accurate accelerated weathering tests, enabling reliable assessment of materials’ UV durability and long-term performance.

2. Versatile Sample Accommodation: Adjustable aluminum and optional 3D holders can securely fit up to 52 standard specimens or custom-shaped samples. This flexibility allows simultaneous testing of multiple samples while maintaining uniform exposure and realistic environmental conditions.

3. Integrated Multi-Environment Testing: The chamber simulates UV light, high temperature (ambient to 90 °C), high humidity (≥95 % RH), and rainfall with 10 automated spray nozzles. These combined environmental stressors replicate real-world conditions, providing customers with actionable durability data.

4. Advanced Control & Data Management: The programmable PID touchscreen allows up to 120 custom programs with 100 steps each, supporting real-time monitoring of temperature, Black Panel Temperature (BPT), irradiance, and spray cycles. USB, RS232, and Ethernet connections facilitate easy data logging, export, and remote monitoring for efficient test analysis.

5. Durable and Low-Maintenance Design: Constructed with SUS304 stainless steel interior and coated steel exterior, the chamber resists corrosion, UV exposure, and high-humidity conditions. UV lamps are easily replaceable, while the automatic water recycling system reduces maintenance and enhances operational efficiency for long-term reliability.
