The world’s most widely-used weathering tester

Weathering Basics Realistic QUV testers with UVA-340 lamps produces the most realistic simulation of sunlight in the short wavelength portion of the ultraviolet spectrum. This region of the solar spectrum is most damaging to durable materials like plastic and paints. The result is a tester that provides excellent correlation with outdoor tests. Sunlight, heat, and moisture cause millions of dollars of material damage every year. The QUV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV can generate the same degradation that occurs...

BLACK PANEL TEMPERATURE CONTROL Uninsulated or Insulated SOLAR EYE IRRADIANCE CONTROL QUV/se The most popular QUV model features 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 calibration according to international standards. QUV/spray The QUV/spray is the same as a standard QUV/se, but also includes a water spray system for enhanced water delivery. Short periods of spray can be used to create a thermal shock. Longer...

UV & Sunlight Simulation “PLUS” LAMPS UV light is responsible for almost all photodegradation of durable materials exposed outdoors. The QUV tester’s fluorescent lamps simulate the critical shortwave UV and reproduce the physical property damage caused by sunlight. Several different types of UV lamps are available for different applications. Q-Lab supplies the highest-quality UV fluorescent lamps available. The technology behind the lamps produces a spectrum that is inherently stable throughout their use. Each manufacturing lot is required to pass a stringent series of tests before it is approved...

Moisture Simulation CONDENSATION: Room Air Cooling 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 condensation and water spray. UV Lamps Spray Nozzle Test Specimen (QUV/spray only) Test Specimen Swing-Up Door CONDENSATION In many outdoor environments, materials are wet more than 12 hours each day. Research indicates...

Specimen Mounting TESTING 3D SPECIMENS Quadrant boxes or panel temperature sensor relocation can help accommodate deep and wide specimens Coatings, plastics, and films are easily accommodated in the QUV tester using standard flat panel specimen holders. Other specimens can be mounted using specialty holders. Q-Lab also offers custom specimen holders for unique needs. All of Q-Lab’s panel holders are designed to meet the requirements of ASTM G154, ISO 4892-3, and other international standards. FLAT SPECIMEN HOLDERS SPECIALTY SPECIMEN HOLDERS Q-Lab offers flat specimen holders in three sizes. All...

Maintenance & Calibration QUV accelerated weathering testers are simple to operate. Programming is intuitive. All models are completely automated and can operate continuously, 24 hours per day, 7 days per week. Designed to be both functional and easy to use, the QUV controller can be programmed in 17 user-selectable languages (English, French, Spanish, Italian, German, Chinese, Japanese, Korean, Czech, Dutch, Polish, Portuguese, Russian, Swedish, Thai, Turkish, and Vietnamese). Additional languages are being added on an ongoing basis. Users can program and store up to 13 tests in memory, which...

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. SPACE SAVER FRAME QUV space saver frames from Q-Lab help preserve space in crowded labs with multiple QUV test chambers. By allowing QUV testers to be stacked two-high, the frames efficiently make use of the same floor space in the lab. Frames are available in two different models for compatibility with all new and...
