QUV

Accelerated Weathering Tester

The QUV accelerated weathering tester reproduces the damage caused by natural 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 accelerated weathering tester exposes materials to alternating cycles of ultraviolet (UV) light and moisture at controlled, elevated temperatures. It simulates the effects of natural sunlight and artificial irradiance using special fluorescent UV lamps in the UVA, UVB, and UVC portions of the spectrum. It simulates dew and rain with condensing humidity and/or water spray.

The World's Most Widely Used Weathering Tester

Test plastics, coatings, and other materials for durability when exposed to outdoor sunlight, heat, and water

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 region of the solar spectrum 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.

Easy to Use

The QUV tester’s simple, proven design makes it easy to install, easy to use, and almost maintenance-free.  The QUV tester is completely automated and can operate continuously, 24 hours per day, 7 days per week.  Other features include.

  • Remarkably simple user interface in 17 user-selectable languages: English, Spanish, French, German, Italian, Japanese, Chinese, Korean, Czech, Dutch, Polish, Portuguese, Russian, Swedish, Thai, Turkish, Vietnamese
  • Built-in Ethernet connection for data logging
  • Comprehensive self-diagnostic warnings and service reminders
  • Quick and easy calibration with patented AUTOCAL system
  • Designed for safety in operation, calibration and maintenance.

Overview

Sunlight, heat, and moisture cause millions of dollars of material damage every year. The QUV® accelerated weathering tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. In a few days or weeks, QUV testers can reproduce the damage that occurs over months or years outdoors. And with its newest model, QUV testers can now reproduce the damage caused by 254 nm UVC light used in sterilization equipment. With thousands of testers in service worldwide, the QUV tester is the world's most widely-used weathering tester.
