The QUV is the World's Most Widely Used Weathering. Explore our advanced technology that ensures accurate material testing for durability against UV light, moisture, and temperature variations. Perfect for industries needing precise performance evaluation.

The QUV tests materials by exposing them to alternating cycles of ultraviolet (UV) light and moisture at controlled, elevated temperatures. The QUV simulates the effects of sunlight with fluorescent UV lamps, and it simulates dew and rain using condensing humidity and/or water spray. Download File

The QUV simulates the effects of sunlight with fluorescent ultraviolet (UV) lamps, and it simulates dew and rain using condensing humidity and/or water spray.

The QUV allows two approaches to moisture simulation. For most applications, condensing humidity is the best way to simulate outdoor moisture attack. All QUV models except QUV/uvc allow a programmed condensation cycle. Because certain applications also require water spray to achieve realistic results, some QUV models can produce both

QUV is the the world's most widely used weathering tester. The NEW QUV/uvc tester features: The new Gen 4 Controller with dual touch-screen displays and 8 languages

The effect is being measured by exposing test samples to varying conditions of the most aggressive components of weathering - ultraviolet radiation, moisture and heat. A QUV test chamber uses fluorescent lamps to provide a radiation spectrum centered in the …

“The QUV with the UVA-340 lamp produces the most realistic simulation of sunlight in the short wavelength portion of the spectrum. The result is a tester that provides excellent correlation with outdoor tests.”

The QUV tester’s simple, proven design makes it easy to install, easy to use, and almost maintenance-free. It operates completely automatically, 24 hours a day, 7 days a week. Features include: • Simple user interface for easy programming • Exposure conditions displayed continuously • Self-diagnostic warnings and service reminders

New Q-SUN "E" Model and Gen 4 QUV Test Chambers. We're excited to unveil brand new xenon arc and UV testing technology. Learn more about the new Q-SUN tester's features below, and get a bonus first look at the Gen 4 QUV Accelerated Weathering Tester.

The QUV accelerated weathering tester is available in a variety of models with different options to suit all testing needs. Additional accessories are available to best integrate the QUV weathering testers and accommodate the space and utilities available in most laboratory spaces.

The QUV® accelerated weathering tester tests materials by exposing them to alternating cycles of UV light and moisture at controlled, elevated temperatures. In a few days or weeks, the QUV tester can reproduce the damage that occurs over months or years outdoors.

The QUV/uvc is a new version of the QUV accelerated weathering tester. The main difference between it and other QUV models is that it is designed to operate UVC lamps, which are functionally identical to those used in ultraviolet germicidal irradiation (UVGI) applications.

The Q-SUN xenon arc tester reproduces the full spectrum of sunlight, including UV, visible and infrared. It is especially useful for testing dyes, pigments, textiles, inks and indoor materials. However, xenon arcs are inherently less stable than fluorescent lamps and water spray is less realistic than the QUV tester's condensation cycle.

The QUV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV tester can reproduce the damage that occurs over months or years outdoors. To simulate outdoor weathering, the QUV tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures.

The QUV test is conducted in accordance with ASTM D4587 and involves exposing coated samples to a combination of ultraviolet (UV) light and moisture to simulate the effects of outdoor weathering.

QUV testing is used to simulate outdoor and indoor sun exposure on surface finishes and coatings and polymers. ASTM G154 is a practice used to do QUV testing. However, there are many test methods requiring QUV testing.

The QUV mimics varying weather cycles to get an accurate picture of how products endure outdoor conditions. The weathering tester complies with many national, international, and industry testing standards and is one of the most widely used weathering testers in the world.

QUV fluorescent UV and Q-SUN xenon arc weathering test chambers simulate and accelerate the three main forces of weathering: sunlight, heat, and moisture. In just a few days or weeks, they can reproduce the damage that occurs over months or years outdoors.

The Q-Lab QUV/SE Arc Test Chamber is an accelerated weathering tester, featuring black panel temperature control that exposes materials to alternating cycles of UV light and moisture. This unit has a 75 x 150 mm (48 specimens) specimen capacity.

QUV weathering makes it possible to accelerate the ageing processes of coatings and thus obtain predictive information about their performance under real environmental conditions. During the QUV test, samples are placed in a test chamber where they are cyclically exposed to the effects of UV light, humidity and temperature fluctuations.
