Key Advantages
1. Realistic Full-Spectrum Sunlight Simulation: Equipped with a 4500 W water-cooled xenon arc lamp and interchangeable optical filters (daylight, window glass, extended UV), the chamber accurately reproduces the natural solar spectrum from 280–800 nm. This ensures reliable simulation of outdoor sunlight exposure in accordance with ISO 4892 and ASTM G155 requirements.
2. High-Precision Light and Climate Control: Irradiance can be precisely set at key wavelengths such as 340 nm or 420 nm, with a wide adjustment range to support different testing intensities. Black panel temperature is controlled within ±1–2 °C, while humidity regulation ensures stable and repeatable aging conditions throughout the test cycle.
3. Uniform Sample Exposure with Rotating Rack: The rotating sample holder design guarantees consistent exposure for up to 42 specimens, minimizing test variability. Uniform airflow and moisture distribution improve repeatability and ensure representative aging and lightfastness results.
4. Advanced Automation and Data Management: An intelligent PID control system continuously monitors and adjusts test parameters, while automatic data recording via Ethernet enables long-term, unattended testing. Remote monitoring and multilingual interfaces improve usability and laboratory efficiency.
5. Efficient and Eco-Friendly Water System: The closed-loop water supply system supports lamp cooling, humidification, and water spray functions. Multi-stage filtration and partial water recycling reduce consumption while maintaining stable and clean spray conditions for long-duration tests.
6. Reliable Safety and Quality Assurance: The chamber is equipped with comprehensive safety protections, including over-temperature protection, over-current protection, water shortage protection, earth leakage protection, and phase sequence protection. All systems are designed and manufactured under strict quality control standards and comply with CE and RoHS requirements.
7. Flexible Customization Capability: The weatherometer can be customized in chamber size, specimen holders (flat, rotary, or 3D), number of radiometers, water spray nozzle layout, control position, viewing windows, and even walk-in configurations. Special designs can support ultra-low temperatures down to –70 °C with reinforced lamp, refrigeration, and sensor systems.
