See LU-0819 - QUV Specifications or the Features Tab for comparative capabilities. QUV/cw: cool white visible light, condensation and SOLAR EYE irradiance control.QUV/uvc: short-wave UVC light and SOLAR EYE irradiance control.QUV/spray: UV, condensation, SOLAR EYE irradiance control and water spray.QUV/se: UV, condensation and SOLAR EYE irradiance control.QUV/basic: UV and condensation (no irradiance control, single touchscreen display).low cost, long life fluorescent UV lamps.The QUV tester is economical to purchase and to operate, because it uses: Quick calibration with patented AUTOCAL system.Self-diagnostic warnings and service reminders.Multicolor LED light for quick “at-a-glance” tester status.Exposure conditions displayed continuously.Dual touchscreen user interface for easy operation and programming in 17 user-selectable languages: English, Spanish, French, German, Italian, Japanese, Chinese, Korean, Czech, Dutch, Polish, Portuguese, Russian, Swedish, Thai, Turkish, Vietnamese.It operates completely automatically, 24 hours a day, 7 days a week. The QUV UV tester’s simple, proven design makes it easy to install, easy to use, and almost maintenance-free.
Visit our standards page for more information. The QUV tester conveniently accommodates up to 48 specimens (75mm × 150mm) and complies with a wide range of international, national, and industry specifications, ensuring the reliability and reproducibility of your test program. This is because the process of evaporating and condensing the water onto the specimens is actually a distillation process, which removes all impurities. The condensation process automatically purifies the ordinary tap water used in the system. The QUV UV test chamber's condensation system realistically simulates dew and accelerates its effect using elevated temperature. Types of damage include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, embrittlement, strength loss and oxidation.ĭew, not rain, is responsible for most of the wetness that occurs in outdoor exposure. The QUV tester’s fluorescent lamps simulate the critical short-wave UV and realistically reproduce the physical property damage caused by sunlight. UV light is responsible for almost all photodegradation of durable materials exposed outdoors. Test plastics, coatings, and other materials for durability when exposed to outdoor sunlight, heat, and water. The World's Most Widely Used Weathering Tester™.
