Key Features of the XL-S-750 Weathering Testing Instrument
High-Power Water-Cooled Xenon Light Source: Powered by a 4500W water-cooled xenon arc lamp to maintain consistent full-spectrum daylight simulation over extended testing cycles.
Superior Exposure Uniformity (Rotating Drum): Standard rotating holder capacity for 42 specimens (95×200 mm). Custom flat-bed racks or 3D specimen holders are also available upon request.
Precision Spectral Irradiance Control: Real-time UV radiometer feedback loop control across 300–400nm broad bandwidth, with customizable 340nm or 420nm narrow-band sensing.
Comprehensive Environmental Control: Integrates mechanical compression refrigeration and automated humidity regulation (50% to 98% RH) alongside BPT monitoring (35°C to 85°C).
Self-Contained Pure Water System: Built-in automatic water supply paired with an integrated water purification system to protect optical filters and lamps from mineral buildup.
Worry-Free Ownership: Every XL-S-750 unit ships with a 3-year full-machine warranty and lifetime technical support, minimizing downtime risk over the equipment's entire service life.

FAQ — Xenon Arc Lightfastness Weathering Testing Instrument
Q: What is the main advantage of a water-cooled xenon lamp over an air-cooled lamp in the XL-S-750?
A: Water-cooled xenon lamps (like the 4500W unit in the XL-S-750) deliver higher irradiance intensity, superior spectral stability, and longer lamp lifespan, making them ideal for high-throughput lightfastness testing and demanding industry standards like ISO 105-B02 and SAE J2412.
Q: Can the XL-S-750 accommodate non-standard or 3D automotive specimens?
A: Yes. While the XL-S-750 comes standard with a 42-position rotating drum holder for optimal uniformity, we offer customizable flat-bed specimen racks and custom mounting fixtures to accommodate thick, curved, or 3D components.
Q: What does the 3-year warranty and lifetime service actually cover?
A: The 3-year warranty covers whole-machine manufacturing defects, including the lamp assembly, control system, and cooling unit. Beyond the warranty period, we continue to offer lifetime technical support and guaranteed access to genuine spare parts, so the instrument remains serviceable and calibration-ready throughout its working life
