AT 15 Color Fastness to Sunlight Test Chamber

AT 15 Color Fastness to Sunlight Test Chamber is a powerful, highly cost-effective, easy to use and convenient to maintain color fastness to light chamber. It uses a air-cooled xenon lamp imported from America and IR window filter both are imported from America , to simulate more real and much better the full spectrum sun light of outdoor through window, ensure the test results obtained from laboratory have a perfect correlation with indoor 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.

AT 15 can meet with all standards requirements from different fields, it can hold 35 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, BSTetc 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.

Characters :

Xenon lamps imported from America can ensure the test results have a good repeatability and comparability. Special rotating-drum design for samples holder ensures 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.
