UV Accelerated Weathering Tester is the world's most widely used ,can be used in more labs throughout the world than any other accelerated weathering tester. It's used widely in the industry, such as printing ink, paint, pastics, print, packaging,motor van, metal, electron, medical... and so on.
UV Accelerated Weathering Tester,simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering - ultraviolet radiation, moisture and heat. A UV accelerated weathering chamber uses fluorecent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters.

Chamber using CNC equipment production, advanced technology, flowing lines, nice appearance
The chamber is made of SUS#304 grade stainless steel plate with 1.0mm thickness and the bottom of the chassis has a water storage tank, and its heating, generating water vapor, hot steam so that can maintain the relative humidity of the test chamber at 95%RH, and to maintain a relatively high temperature.
The test piece is actually constitute the side walls of the chamber, so that the back of the specimen exposed to the cold in the indoor air, indoor air as led to the specimen surface temperature drops to a level lower than the steam temperature of a few degrees. This different temp is led to the emergence of the specimen, its surface is always in the entire condensation cycle generating liquid water condensation.
This condensation product is very stable, pure distilled water, pure water to improve the reproducibility of the test while avoiding stains. inside the duct single round-robin system, one only imported axial fan to improve air flow, heating capacity significantly improved chamber temperature uniformity
Lamps:UVA or UVB lamp, 40W/each lamp
UVA-340 is the best choice for the simulated solar ultraviolet excellent analog critical short wavelength range of the solar spectrum, the wavelength range spectral range 315 to 400nm. UVA-340 produced only UV wavelength spectrum can be found in the sun.
Although these natural wave length UV light can maximize the accelerated test, but it will also cause some of the material does not match the together the actual degradation of destruction.
Lamp life:1600~1800h(Imported lamps).
Pipe run after every 400 hours, the upper and lower lamp replacement in turn, to ensure that each lamp uniform radiation, while ensuring that any time the output power is always maintained at the average value, this average is always remained relatively stable, Do not change over time.
In the light after the 400-450 - h, each row of lamp tubes need to change a fluorescent tube
When replacement lamp tubes, should wipe dry water dish and clean, and avoid the formation of scale
Water and consumption:clean water or distilled water 8 liters / day
The optical level of the reaction is not sensitive to changes in temperature, however, the rate of secondary reactions and the consequent change in temperature are closely related. In general, as the temperature increases, the reaction speed increases, so the UV exposure test, it is very important to control the temperature, the more important is to accelerate the test temperature and the test material used in the practical application match the highest temperature encountered. The temperature of the device is set to ultraviolet process in 50 ℃ ~ 70 ℃ at any point, depending on the illumination level and temperature of the indoor environment. Temperature control device is adjusted by a microcomputer having calculation functions within the device to direct the air heater, water heater, etc. to complete a series of system.
With increasing temperature, moisture damaging the material will increase dramatically. Therefore, as in the wet too, the temperature control is a basic requirement. Furthermore, the effect is to produce the acceleration required to maintain the high temperature environment in wet process. Therefore the condensation temperature in the process is set to 40 ℃ ~ 60 ℃ any point.

2, temperature control and lighting system is completely independent
3, the output power by the microcomputer temperature control algorithms to achieve high precision and high efficiency power efficiency
4, with anti-over-temperature heating system features:
(a) blackboard with color touch screen temperature control device or digital programming temperature controller buttons control the heating power output by the microcomputer calculus, PID self-tuning, monitoring blackboard using standard PT100 temperature sensor.
(b) sink temperature with color touch screen programming temperature controller heating Korea, sink located in the lower box, built-in electric heaters plus. During the test, the test section is a dark condensation process which produces saturated steam cabinets requires higher temperatures encountered when the relatively cold vapor sample surface, dew condenses on the surface of the template
