The household air-cooled xenon arc aging tester is a household experimental equipment independently developed and produced by our company QINSUN Instruments Co., Ltd. It can be compared with ATLAS 220 xenon arc aging machine. It is a large capacity light resistant aging tester for textile testing. Equipped with sample holder irradiation, temperature sensor and long-lasting filter technology.

In addition, what is the difference between the broadband and narrowband irradiance settings in the aging test for xenon lamps? For xenon arc aging tests and accelerated UV weathering tests, radiation settings that do not reflect a specific wavelength or range of wavelengths do not fully reflect the information. There are two ways to adjust the radiation in the xenon lamp aging test chamber.
Narrowband radiation is set at 340nm and 420nm, representing a band range of 1nm, based on a single wavelength value (e.g. approximately 340nm each ?nm). Narrowband irradiance is measured in nanowatts per square meter. Usually written as W/(m2*nm)W/m2/nm, or W*m-2?nm-1.
Broadband radiation settings (commonly referred to as TUV or totalUV) refer to the integration of radiation wavelengths across the entire band range, such as 300-400nm (lab acceleration) or 295-385nm (outdoors). Datherefore, the broadband irradiance value is usually much larger than the narrowband irradiance value. The broadband radiation can be written as W/m2 or W? Expressed in per square meter. m-2.
The same radiation, ultraviolet rays are more harmful to fabrics! By using a low-voltage mercury arc to excite fluorescents to emit ultraviolet light, the light source can produce a continuous spectrum in a narrow wavelength range, usually with only one peak. Although the simulation effect of the ultraviolet artificial weathering experiment is not good, the acceleration effect is very good.
The xenon aging test in the xenon lamp aging test chamber is considered a better experimental method to simulate climate aging. Xenon arc light source is one of the light sources that are currently well imitated. It has been theoretically concluded that the xenon lamp is superior to other light sources for a long time.
