1. Principle:

Xenon lamp aging tester and UV aging tester are more widely used accelerated aging test equipment, the two test equipment testing principle is completely different. Xenon lamp aging tester simulates all the spectrum of sunlight, including ultraviolet (UV), visible light and infrared (IR), xenon lamp spectrum in the range of 295nm to 800nm basically coincides with the spectrum of sunlight. This means that xenon lamps are used to test many products that are sensitive to the long wavelengths of UV, visible light and IR. UV weathering chambers, on the other hand, use fluorescent UV lamps to mimic the damaging effects of sunlight on durable materials. This is different from the xenon arc lamps mentioned earlier, fluorescent UV lamps are electrically similar to the general lighting cold fluorescent lamps, but can generate more ultraviolet light rather than visible or infrared light.

2. Use:

Xenon lamp aging tester adopts xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments, which can provide corresponding environment simulation and accelerated test for scientific research, product development and quality control. And, the UV aging tester mainly adopts fluorescent UV lamp as the light source, and accelerates the weathering test of materials by simulating the UV radiation and condensation in natural sunlight, in order to obtain the results of material weathering. It can simulate the environmental conditions such as UV, rain, high temperature, high humidity, condensation, darkness, etc. in the natural climate, by reproducing these conditions, combining them into one cycle and letting it perform automatically to complete the cycle times.

Water cooling is a method to dissipate the heat generated inside the xenon aging tester through a water cooling system. The water cooling system consists of a water pump, a water tank, a radiator, etc. The principle is that the coolant containing the heat generated inside the xenon aging tester is cooled by the radiator. The coolant used in the water cooling system is usually pure water or water with added preservatives.
