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

Model QUV/spray
The QUV/spray tester has the same functions as a standard QUV/se, but also includes a water spray system. Short periods of spray can be used to create a thermal shock. Longer periods can be used to achieve mechanical erosion. The QUV/spray tester can be set to produce: UV alone, spray alone, or condensation. Deionized water is recommended for all spray applications.
Model QUV/cw
Some industry test methods specify the use of cool white fluorescent lamps for indoor photostability testing. To reproduce these indoor light conditions, the QUV/cw uses ordinary cool white fluorescent lamps. It has a SOLAR EYE irradiance control system that monitors and controls visible light output, rather than UV.
