Q-LAB Q-SUN XE-2 Xenon Weathering Tester

Q-LAB Q-SUN XE-2 Xenon Weathering Tester

In the textile, footwear, plastics, and coatings industries, accurately evaluating colorfastness and weathering resistance under sunlight exposure is vital to proving product quality. The Q-LAB Q-SUN XE-2 is a professional accelerated xenon arc weathering test chamber featuring a rotating drum specimen rack.

Engineered by Q-LAB (USA)—the world’s most trusted name in weathering test equipment—the Q-SUN XE-2 is the ideal solution to meet the most demanding textile industry standards (such as ISO 105-B02) alongside other rigorous international testing specifications.

Key Differences & Outstanding Features of the Q-SUN XE-2

Rotating Drum Specimen Technology for Absolute Uniformity

Unlike the XE-1 or XE-3 models which utilize flat-array specimen trays, the Q-SUN XE-2 positions test specimens on a continuously rotating drum around a centrally located xenon arc lamp. This design guarantees:

• 100% of the specimen surfaces receive absolutely uniform levels of light irradiance, temperature, and relative humidity, completely eliminating position-to-position variability.
• Homogeneous exposure, making it exceptionally well-suited for light-sensitive materials such as woven fabrics, sewing threads, footwear leather, and thin films.

Premium Full-Spectrum Light Filtering System

The equipment utilizes an 1800W air-cooled xenon arc lamp, combined with Q-LAB’s proprietary specialized optical filters. This system accurately reproduces:

• Outdoor Environments: Utilizes Daylight filters to simulate direct, natural outdoor sunlight.
• Indoor Environments: Utilizes Window Glass filters to simulate sunlight filtered through window panes (a mandatory requirement for home textiles and apparel standards).

Automatic Irradiance Control with SOLAR EYE

The intelligent SOLAR EYE control system allows users to select and precisely control the desired irradiance intensity (at 340 nm, 420 nm, or TUV wavelengths). The system automatically compensates for lamp degradation over time, ensuring test results remain highly repeatable.

Strict Temperature and Relative Humidity Control

• Relative Humidity (RH): The Q-SUN XE-2 precisely controls relative humidity within the test chamber to simulate humid tropical climates—a critical factor when assessing the fading of textile dyes.
• Temperature: Enables simultaneous monitoring and control of chamber air temperature and black panel temperature (BPT/BST).

Typical Applications of the Q-SUN XE-2

Thanks to its rotating drum design and excellent humidity control capabilities, the Q-SUN XE-2 serves as a vital tool in these fields:

• Textiles & Footwear: Lightfastness and weathering colorfastness testing for fabrics, yarns, synthetic leather, and outdoor sportswear or protective apparel.
• Plastics & Polymers: Evaluating degradation, embrittlement, and yellowing of polymer films and packaging materials.
• Inks & Colorants: Testing the color stability of printing inks used on textiles, paper, and product labels.
• Automotive Components: Testing interior car components (upholstery, carpeting) exposed to sunlight coming through windshields.

Why Businesses Should Invest in the Q-SUN XE-2

• Exceptional Accuracy: The rotating drum mechanism completely eliminates thermal and irradiance blind spots inside the chamber, delivering 100% consistent results.
• Low Operating Cost: Q-LAB’s air-cooled xenon lamps offer economical replacement costs and do not require complex, expensive water-cooling filtration systems like water-cooled alternatives.
• Easy Monitoring: Built-in Ethernet connectivity enables rapid test report exporting, making it ideal for export quality control and certification processes.
