Xenotest 440 - Atlas

Advanced Xenon Arc Weathering Testing with the Xenotest 440

The Atlas Xenotest 440 is a highly versatile xenon arc weathering instrument designed for fast and economical testing of a variety of materials. This mid-sized, air-cooled xenon device sets a new standard in weathering testing technology, combining innovative features with exceptional performance for accelerated material testing applications.

Revolutionary XenoLogic™ Technology

The Xenotest 440 utilizes XenoLogic™, a revolutionary twin-lamp operating technology that enables high irradiance levels of up to 120 W/m² of total UV radiation. This advanced technology provides extended lamp service life, with the two xenon lamps combined lasting over 4000 hours under standard testing levels of 40-60 W/m². This significantly increases instrument uptime and reduces lamp operating costs by as much as 30% or more.

Exceptional Sample Capacity and Versatility

The Xenotest 440 test chamber provides exceptional capacity for testing various materials and sample sizes. It accommodates 38 narrow test positions (13.5 x 4.5 cm) suitable for textiles, leather or paper specimens, 33 wide positions (10 x 6.8 cm) for plastics, paints and coatings, 22 wide & long positions (13.5 x 5.5 cm) for technical textile and automotive interior specimens, and 19 or 11 extra-long positions for technical textiles and plastics specimens.

Advanced Control and Monitoring Features

The instrument features selectable temperature control either by Chamber Temperature (up to 65°C) or by Dual Control with both Chamber Temperature and Black Standard Temperature (up to 115°C) simultaneously. It includes on-rack XENOSENSIV® RC-300-400 BST for measuring and controlling irradiance in the wavelength range 300-400 nm and temperature at specimen level. The system also features ultrasonic humidifiers to reduce water consumption and an integrated 60-liter water reservoir for the sample spray system.
