Sun Xenon Arc Tester Weathering Testing Instruments

The Sun Xenon Arc Tester Weathering Testing Instruments feature a durable stainless steel test chamber designed to provide stable and uniform exposure conditions. The interior workroom is manufactured from SUS304 stainless steel, which offers excellent resistance to corrosion and high humidity environments, ensuring long service life even under continuous weathering cycles. A rotating sample holder inside the chamber supports up to 42 specimens and slowly rotates around the xenon lamp to guarantee uniform irradiance distribution across all samples. This rotating structure ensures that each specimen surface receives consistent light exposure and water spray, providing representative and comparable test results.

Performance Advantages

1.Full-Spectrum Solar Simulation: A 4500 W water-cooled xenon arc lamp combined with optical filters accurately reproduces natural sunlight across the 280–800 nm wavelength range. This full-spectrum simulation allows reliable evaluation of UV degradation, color fading, and long-term weathering effects on various materials.

2.Precise Environmental Control: The chamber maintains black panel temperatures typically between 35 °C and 85 °C with high stability, while humidity conditions can be adjusted across a wide range to simulate realistic outdoor climates. Integrated PID control ensures consistent irradiance and temperature throughout long testing cycles.

3.Uniform Sample Exposure: A rotating specimen holder supports up to 42 samples and ensures that each specimen receives uniform light intensity and water spray during testing. This design improves the repeatability and comparability of aging results.

4.Automated Water and Cooling System: The automatic water inlet and closed-loop circulation system continuously supplies purified water for spray and humidification while recycling condensate to reduce water consumption. Water-cooled xenon lamps maintain stable light output and extend lamp service life.

5.Advanced Monitoring and Data Traceability: Built-in radiometers and temperature sensors continuously measure irradiance and specimen surface temperature. Data can be recorded, exported, and monitored remotely through Ethernet connectivity, supporting modern laboratory data management requirements.

6.Durable Construction and Safety Protection: The chamber features a corrosion-resistant SUS304 stainless steel interior and a reinforced steel exterior structure for long-term reliability. Multiple safety systems—including over-temperature protection, water shortage protection, electrical leakage protection, and phase sequence protection—ensure safe and stable operation during extended weathering tests.

Equipment Specifications

Typical Tests Performed by the Sun Xenon Arc Tester Weathering Testing Instruments
The xenon arc weathering tester can perform a wide variety of accelerated environmental aging tests. For example, materials may be exposed to continuous xenon light at irradiance levels around 60–120 W/m² while maintaining black panel temperatures near 65 °C to evaluate long-term sunlight degradation. Humidity cycles ranging from approximately 50% to 95% RH can be introduced to simulate damp outdoor conditions, while periodic water spray cycles lasting several minutes every hour reproduce rainfall or condensation effects. These combined conditions help engineers analyze color fading in textiles, cracking in plastics, surface chalking in coatings, and durability loss in rubber or automotive components. By reproducing years of outdoor exposure within a few weeks or months, the chamber allows manufacturers to predict product lifespan, optimize material formulations, and ensure product reliability before market release.

FAQs on the Sun Xenon Arc Tester Weathering Testing Instruments

Q1: What irradiance range can the xenon arc tester achieve?

The standard irradiance range of the xenon arc weathering tester is typically about 35–150 W/m². If your application requires a different irradiance level or specific wavelength monitoring such as 340 nm or 420 nm, the system can be customized to match your testing requirements.

Q2: Does the chamber provide alarms for abnormal operating conditions?

Yes. The tester includes multiple built-in safety protections such as over-temperature alarms, water shortage detection, and electrical protection. Audible alarms are standard, and visual alarm indicators can also be configured if required.

Q3: Can the chamber be customized for special sample holders or viewing windows?

Yes. LIB supports customization of sample racks, test ports, and optical glass viewing windows according to your testing needs. Standard modifications usually do not affect delivery time, while special customization may extend the schedule slightly to ensure precise manufacturing and reliable performance.
