UV Accelerated Weathering Tester.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, moisture and heat.
UV test chamber use fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters. Based on your testing sample’s size,

FAQ
●Question 1. Explain what is the relationship between UVA and nm ?
●Answer: The wavelength range: 315～400nm, we named it’s UVA light.
●Question 2. UVB lamps degrade material quicker than UVA lamps … correct ? Why ?
●Answer: The wavelength range: 280～315nm, we named it’s UVB light. Because it’s short wavelength, It maks the testing material with a faster degradation.
●Question 3. What is UV Weathering Test Machine Irradiance ?
●Answer: Irradiance is the unit, the lighting/ lamp’s strength. Unit: W/m2
UV aging test equipment is widely used in paintings, plactics, textile industry.
