The weatherability testing xenon machine allows ambient to 100 °C ±2 °C control, while the black panel temperature (BPT) ranges from 35–85 °C ±2 °C, and humidity is adjustable from 50% to 98% RH, replicating complex weather cycles. Rotating and adjustable sample holders ensure uniform exposure across coatings, plastics, textiles, and automotive parts. Programmable light/dark and condensation cycles accelerate testing, revealing color fastness, cracking, fading, and material degradation in weeks instead of years. Fully compliant with ASTM G151/G155 and ISO 4892 standards, this machine provides repeatable, high-precision results, empowering engineers and designers to validate product longevity and performance under extreme environmental stress.

Highlights of the Weatherability Testing Xenon Machine
High-Efficiency Water-Cooled Xenon Lamp
The 4500 W xenon arc lamp uses a dedicated water-cooling circuit to remove thermal buildup at the source, maintaining a stable spectral output and preventing heat-induced drift. This design delivers consistent irradiance in the 35–150 W/m² range, providing long-term uniformity essential for comparative durability studies.
Black Panel Temperature (BPT) – True Thermal Load Indicator
The BPT reflects the combined effects of chamber hot-air convection and the heat generated directly by xenon irradiation, representing the maximum temperature a sample may experience during testing. The system maintains 35–85 °C ±0.5 °C, ensuring highly reliable assessment of materials' thermal-photonic response under accelerated aging.
Independent Dual Waterway + Advanced Spray System
The machine features two independent waterway systems: one dedicated to lamp cooling and the other to humidity and spray functions. The spray system uses precision nozzles to reproduce rainfall, surface erosion, and thermal-shock events. By extending the environmental conditions that can be simulated, it enables combined UV, heat, moisture, and water impact testing in one device.
Intelligent Multi-Function Controller
The touchscreen controller integrates irradiance feedback, temperature/humidity regulation, program editing, and remote access. Users can run custom cycles or activate presets for ASTM and ISO methods. Real-time monitoring ensures the system maintains consistent exposure conditions across long-duration tests.
