Ⅰ. Introduction:

XD-21-860 is a powerful, highly cost-effective, easy to use and convenient to maintain xenon test chamber. It uses a air-cooled xenon lamp and relevant daylight filter (both are imported from America ),to simulate more real and much better the 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. 

XD-21-860 Xenon Test Chamber 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 status at any time. All running parameters can be exported to computer directly through the USB interface.

Ⅲ. Characters：

◆ Xenon lamps imported from America can ensure the test results have a good repeatability and comparability.

◆ Special rotating-drum design for samples holder ensure each sample can obtain the same and uniform irradiance during the whole test.

◆ Irradiance energy can be accurately controlled. The "Closed-Loop" 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 broad band（from 300nm～400nm or from 300nm～800nm）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 10 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 black panel temperature by themselves.

◆ With High precision Pt100 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）, big deviation of irradiance，shortage of spraying water, abnormal lamp power，big error of humidity.

◆ 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.
