Testing at high irradiance can be an effective way to achieve faster results from your accelerated weathering test program. Q-Lab’s new UVA-340+ and UVB-313EL+ fluorescent UV lamps enable you to perform high-irradiance testing with improved lamp life to get the most out of your QUV.
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 spectrum and reproduce the physical property caused by sunlight. Several different types of UV lamps are available for different applications, and optical filters are not required.
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 for sale. The result is that the QUV tester provides a consistent, stable spectrum, year after year.
With thousands of testers in use worldwide, the QUV the world's most widely used weathering tester. It reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV UV tester can reproduce the damage that occurs over months or years outdoors.
To simulate outdoor weathering, the QUV accelerated tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It simulates the effects of sunlight using special fluorescent UV lamps. It simulates dew and rain with condensing humidity and/or water spray. The QUV accelerated weathering tester is the simplest, most reliable, and easiest to use weathering tester available.
Q-Lab is a global provider of material durability testing products. They design and manufacture standard test substrates as well as weathering and corrosion test equipment. In addition, they provide test services including outdoor exposure at benchmark facilities in Florida and Arizona, as well as accelerated laboratory testing services in Florida, Germany, and China. Their products and services are used by material scientists and technicians around the world in many industries.
