Specifications

The UV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the UV tester can reproduce the damage that occurs over months or years outdoors.

To simulate outdoor weathering, the UV Accelerated Weathering 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 UV test machine is the simplest, most reliable, and easiest to use weathering tester available. With thousands of testers in use worldwide, it is the world's most widely used weathering tester.
