QUV - The World's Most Widely Used Weathering Tester
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 over months or years outdoors. 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.
Will your product last outdoors? Don’t guess when you can test!
UV light is responsible for almost all photodegradation of durable materials exposed outdoors. The QUV tester’s fluorescent lamps simulate the critical short-wave UV and realistically reproduce the physical property damage caused by sunlight. Types of damage include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, embrittlement, strength loss and oxidation.
Dew, not rain, is responsible for most of the wetness that occurs in outdoor exposure. The QUV UV test chamber's condensation system realistically simulates dew and accelerates its effect using elevated temperature.
The condensation process automatically purifies the ordinary tap water used in the system. This is because the process of evaporating and condensing the water onto the specimens is actually a distillation process, which removes all impurities.
The QUV tester conveniently accommodates up to 48 specimens (75mm x 150mm) and complies with a wide range of international, national, and industry specifications, ensuring the reliability and reproducibility of your test program.
Easy to Operate
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.
The dual, full-color touchscreen displays on QUV testers allow for real-time viewing of test parameters and performance along with control of tester operation and settings. The multi-color LED light indicates, at a quick glance, the tester’s operational status. The screens are fully redundant, allowing for operation even in the unlikely event that one of them fails. Tester performance data is recorded automatically and easy to export via USB drive. Software updates can also be performed quickly using the USB port without interrupting tester operation.
