Atlas Material Testing Technology, the global leader in weathering technology and services, has introduced a new weathering instrument suitable for performing accelerated testing on a variety of materials.
Debuting at the K 2013 show recently in Düsseldorf, German, the Xenotest 440 sets a new standard in economical, mid-sized, air-cooled xenon devices. Designed for fast and economical testing, the Xenotest 440 combines new XenoLogic™ lamp operating technology with an efficient design that includes ultrasonic humidifiers to reduce water consumption.
XenoLogic is a revolutionary new twin-lamp operating technology, which enables the instrument to achieve high irradiance levels of 120 W/m2 of total UV radiation. By testing at higher irradiance levels, test times can be significantly reduced, compared to standard weathering tests.
In addition to its high irradiance functionality, XenoLogic provides another significant advantage: an extended lamp service life. How does it work? XenoLogic continuously synchronises two 2200 W xenon lamps inside the chamber at the lowest possible stress level, which leads to optimised lamp service life and maximised light efficiency. With this new technology, the two xenon lamps combined can last over 4000 hours under standard testing levels of 40 - 60 W/m2. This increases instrument uptime and reduces lamp operating costs by as much as 30% or more.
The Xenotest 440 test chamber provides exceptional capacity for an array of materials and sample sizes:
- 38 narrow (13.5 x 4.5 cm) test positions suitable for textiles, leather or paper specimens.
- 33 wide (10 x 6.8 cm) test positions suitable for plastics, paints and coatings specimens.
- 22 wide & long (13.5 x 5.5 cm) test positions suitable for technical textile/automotive interior specimens.
- 19 or 11 extra-long test positions suitable for technical textiles/plastics specimens.
With its wide-ranging testing capabilities and its ability to handle material-specific specimens, the Xenotest 440 is among the most versatile instruments available, designed to cover today's and tomorrow's most commonly used industry standards (ISO, ASTM).
