Product Description
UV Weathering Test Chamber
The usage
UV weathering test chamber is equipped with a fluorescent UVA/UVB lamp which can simulate the UV spectra of sunlight,exposes materials to alternating cycles of UV light and moisture at controlled,elevated temperatures.It`s used to test types of damages include colour change,gloss loss,chalking,cracking,crazing,hazing,blistering,strength loss and oxidation.
Applications
- Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature.
- To get the results of damage after several days or weeks which is equal to expose to outside for a few months. The damages include fading, discoloration, brightness down, powder, crack, blur, brittle, strength decreases and oxidation.
- Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.
Features
- Different wavelengths of UV can be selected according to different test requirements.
- The unique condensing function simulates the damp erosion of the outdoor.
- Temperature can ba controlled at a fixed value and can be monitored.
- The light intensity is optional,and selection of the selection of the irradiated intensity can get the accuracy and repeatability of the test results.
