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
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.
