Test Chamber
Applications:
UV accelerated weathering test chamber simulates damaging effects
of long term outdoor exposure of materials and coatings by exposing
test samples to varying conditions of the most aggressive
components of weathering - ultraviolet radiation, humidity and
heat. A UV weathering test chamber uses fluorescent lamps to
provide a radiation spectrum centered in the ultraviolet
wavelengths. Moisture is provided by forced condensation, and
temperature is controlled by heaters.
