QUV Models

QUV models: QUV/se | QUV/spray | QUV/basic | QUV/cw
View LU-0813 specification sheet for comparative capabilities.


QUV/se
The most popular QUV model features the Solar Eye Irradiance Control for precise maintenance of UV light intensity. The QUV/se uses a proven condensation mechanism to simulate outdoor moisture attack. It allows faster, more reproducible testing, longer lamp life, and ISO calibration. With the QUV/se, state-of-the-art accelerated weathering is available in an affordable tester that is easy to use

QUV/spray
QUV Spray

The QUV/spray is the same as a standard QUV/se, but also includes a water spray system consisting of spray nozzles, piping, controls and drain.

Short periods of spray can be used to create a thermal shock. Longer periods can be used to achieve mechanical erosion. The QUV/spray can be set to produce the following conditions:  UV alone, spray alone, or condensation. Deionized water is recommended for most spray applications.


QUV/basic
QUV basic

This is a simplified version of the QUV for the lab where economy is critical. Irradiance is controlled by periodic lamp replacement and repositioning. The QUV/basic has a condensation system for moisture simulation. It does not have water spray.

The QUV/basic does not have the Solar Eye Irradiance Control system. Consequently, the light intensity cannot be adjusted or calibrated. This means the QUV/basic cannot be used for high irradiance testing.

We recommend the QUV/basic for comparative exposures where the test specimens and the control specimens are exposed at the same time in the same tester.


QUV/cw

Some industries have test methods that specify the use of cool white lamps for indoor photostability testing. To reproduce indoor light conditions, the QUV/cw has a Solar Eye Irradiance Control system which has been modified to monitor and control the light output of cool white fluorescent lamps. See Q-Lab Bulletin LU-0823, QUV/cw Cool White Photostability Tester for more information.

The QUV/cw uses cool white lamps to simulate indoor environments, such as the overhead fluore-
scent lighting typically found in offices. It also meets ISO, ANSI and ASTM test methods for indoor photostability testing.
