High-performance xenon weathering tester with ASTM D 7869 capability
The IWASAKI XER-W83-A EYE Super Xenon Tester is designed for accelerated weathering evaluation using a water-cooled 7.5 kW xenon arc lamp. Three irradiation modes provide control ranges from 20 to 180 W/m² over the 300–400 nm measurement range, supporting controlled evaluation of coatings, plastics, textiles, automotive materials, and other weather-exposed materials.
The IWASAKI XER-W83-A EYE Super Xenon Tester is a high-performance xenon arc weathering system designed for controlled accelerated evaluation of material weatherability.
A water-cooled 7.5 kW xenon arc lamp and optical filter system provide controlled irradiation for weathering tests that simulate solar exposure. The XER-W83-A supports standard-, medium-, and high-intensity irradiation modes together with temperature, humidity, spray, and dark-cycle control.
IWASAKI developed the XER-W83-A with a temperature and humidity control program and a specialized optical filter designed to provide a spectrum closer to sunlight. Fine control of irradiation, shower, temperature, and humidity conditions supports weathering evaluations with improved correlation to outdoor exposure.
A 10.4-inch touch panel supports test-condition setup and monitoring, while programmable test segments can combine irradiation, shower, and dark cycles. Optional LAN-based remote monitoring and operation are also available.
A specialized optical filter and temperature/humidity control program support ASTM D 7869 weathering evaluation for transportation-equipment coating materials.
Standard-, medium-, and high-intensity irradiation configurations provide control ranges from 20 to 180 W/m² over the 300–400 nm measurement range.
The xenon lamp and optical filter system provides controlled spectral exposure designed to improve correlation with natural outdoor weathering.
Irradiation, irradiation with spray, and dark-cycle segments can be combined and repeated to reproduce complex accelerated weathering test sequences.
Three rotating-drum configurations support different irradiation conditions while providing 90% or higher irradiation uniformity.
The large touch interface simplifies test-condition setup and status monitoring, with improved data logging for test management.
Controlled temperature, humidity, irradiation, and shower conditions enable repeatable environmental exposure programs for weatherability evaluation.
An optional LAN-based remote function allows operators to monitor test progress and equipment status from a PC on the connected network.
