Atlas Unveils NextGen Xenotest 220 and 440 for Accelerated Weathering Testing

­Atlas, the global leader in weathering testing technology, introduces next generation Xenotest® 220 and 440 xenon-arc instruments featuring expanded test method support, and improved integration with lab networks. Designed for demanding applications in the polymer, coatings, automotive and textile industries, the upgrades simplify operation while enhancing test consistency and day-to-day reliability.  

The air-cooled, rotating-rack Xenotest 220 and 440 simulate the effects of sunlight, heat, and moisture to accelerate material testing under controlled conditions. Their high sample capacity in a compact footprint, and robust performance make them a trusted platform for lightfastness and weathering evaluations.  

Expanded Standards and Method Support
The range of preloaded test protocols has been significantly extended and now covers all commonly used ASTM, AATCC, GB/T, and SAE standards. A key highlight of the new Xenotest 440 is its capability to perform the globally recognized American automotive tests SAE J2412 for interior components and SAE J2527 for exterior components. Together with its highly flexible specimen holder system, the Xenotest 440 has become a truly compact all-rounder for automotive testing.

"One of my favorite features is the extension of the test libraries," said Dr. Oliver Rahäuser, Senior Product Manager at Atlas. "It makes setting up your Xenotest significantly easier."    

Unified Control and Refined Monitoring
A redesigned 10.1-inch XenoTouch® II interface improves visibility and navigation of the Xenotestwhile aligning with the Atlas Ci Weather-Ometer® and SUNTEST® instruments – offering a consistent operator experience across all Atlas’s xenon-arc platforms. Set-point monitoring functionality allows users to define all test parameter tolerances and receive real-time alerts when conditions drift beyond limits.  

Remote Data Access and Reporting
WXView® II connectivity enables secure, cloud-based access to active and historical test data. Users can monitor progress across locations, compare results, and generate standardized PDF reports to support quality-assurance and audit documentation.     

High Throughput in a Compact Footprint
Both models accommodate up to 38 specimens, with supported formats ranging from 90 × 75 mm to 285 × 75 mm and up to 10 mm thick – allowing labs to test everything from thin films to molded parts without requiring the footprint of larger systems. The new Xenotest 220 and 440 also feature an updated exterior design that reflects Atlas’s new industrial styling, bringing visual consistency across its entire xenon-arc portfolio.

The new models are now available through Atlas and its global distribution network. For more information, go here.
