Xenon Weathering Fastness Tester

Product Description

Application

The XWT is the Best & Latest Technology of Xenon Instrument which is used to determine color fastness to light, weather and light aging of various colored textiles and other materials by simulating both light and dark cycles and nature weather conditions by specimen holders and rack sprays and long-arc-xenon lamp equipped. 

It uses a air- cooled xenon lamp and relevant daylight filter both are imported from USA, to simulate real and much better full spectrum sun light of outdoor, ensure the test results obtained from laboratory have a perfect correlation with outdoor application.Furthermore, the samples holder is designed with a special rotating drum to ensure each sample can obtain the same and uniform irradiance during the whole test.

It can meet with all standards requirements from different fields, it can hold 22 pieces samples,not only has spray function, but also can control the relative humidity of working room. Operator can set all required test parameters Irradiance, test time, BPT, BST etc through the touch screen, and can check its running statusat any time. All running parameters can be exported to computer directly through the USB interface.

Features:

• Xenon lamp and relevant filter imported from USA can ensure the test results have a good repeat ability and comparability.
• Special rotating-drum designed for samples holder to ensure each sample can obtain the same and uniform irradiance during the whole test.
• Irradiance energy can be accurately controlled.
• The"Sun Eye"control system can automatically compensate the change of light intensity caused by ageing or other factors.
• Can choose narrow band at 340nm or at 420nm or broadband from 300nm 400nm to control irradiance.
• Affordable air-cooled xenon lamp, the lifetime can reach 1,500 hours.
• Can choose three different filters Daylight, Window glass, Extended UV to meet different test requirements.
• The test procedures can be programmed freely; can set 9 programs and save 6 predetermined programs in one time. Every program includes up to 10 segments for setting parameters.
• Can set and control precisely and automatically the relative humidity of working room.
• Can set the cumulative energy total irradiance energy obtained by sample to finish a test procedure.
• With spray function, can set spray time and spray interval time.
• Users can easily calibrate and adjust the irradiance or the blackboard temperature by themselves.
• With High precision Pt 100 Temperature sensor. BPT black panel temperature , BST black standard temperature and working room temperature can be set and controlled precisely and automatically during the whole process
• Alarm and protection function Over temperature BPT,BST, working room, cooling water , over heating load, big error for irradiance, over standard of pure water conductivity, auto shut-down protection when opening door.
• Touch screen and user-friendly operation interface allow operator to set the test parameters and monitor all the test process easily.
• Real-time data can be collected and recorded. The incidental USB connector allow users to download the test data EXCEL format directly, achieving unattended operation.
