The QUV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV UV tester can reproduce the damage that occurs over months or years outdoors.
To simulate outdoor weathering, the QUV accelerated tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It simulates the effects of sunlight using special fluorescent UV lamps. It simulates dew and rain with condensing humidity and/or water spray.
The QUV accelerated weathering tester is the simplest, most reliable, and easiest to use weathering tester available. With thousands of testers in use worldwide, it is the world's most widely used weathering tester.
Model QUV/basic
This is a simplified version of the QUV tester for the lab where economy is critical. The model QUV/basic uses fluorescent UV lamps and a condensation system for moisture simulation. The model, however, does not include the SOLAR EYE irradiance control. Consequently, the light intensity cannot be adjusted or calibrated. This means the QUV/basic tester cannot be used for high irradiance testing. In addition, periodic lamp replacement and repositioning is required.
Q-Lab recommends the QUV/basic tester for comparative exposures where the test specimens and the control specimens are exposed at the same time, in the same tester.
Model QUV/se
The most popular QUV model features the SOLAR EYE Irradiance Control, for precise maintenance of UV light intensity. The QUV/se tester uses a proven condensation mechanism to simulate outdoor moisture attack.
The SOLAR EYE system is a precision control system that automatically maintains light intensity through a feedback loop. The controller monitors UV intensity and compensates for lamp aging and variability by adjusting power to the lamps. The SOLAR EYE system provides:
Controlled irradiance
Longer lamp life
Faster results
More reproducible and repeatable testing
ISO calibration
