Applicable Industries:
The UV Weathering Test Machine is the most widely used in laboratories around the world. It is ideal for testing materials and coatings in various industries such as printing ink, paint, plastics, packaging, automotive, metal, electronics, medical, and more.
This machine simulates the harmful effects of long-term outdoor exposure by exposing test samples to the most aggressive components of weathering—ultraviolet radiation, moisture, and heat. It uses fluorescent lamps to provide a radiation spectrum centered in the ultraviolet range. Moisture is provided through forced condensation, and temperature is controlled using heaters.
