Lab Programmable Digital UV Accelerated Aging Test Chamber
This professional testing chamber simulates the damaging effects of sunlight, rain, and dew to accelerate material aging studies. Using fluorescent UV lamps to reproduce solar radiation and condensation to mimic moisture, it exposes test samples to alternating cycles of light and moisture at controlled temperatures.
In just days or weeks, this UV chamber can reproduce damage that would typically take months or years to occur under natural outdoor conditions, helping you select better materials and understand how formulation changes affect product durability.
Equipment Applications
- Simulates damaging effects of sunlight, moisture, and temperature on various materials
- Identifies aging symptoms including fading, gloss loss, strength reduction, cracking, peeling, chalking, and oxidation
- Accelerated testing reproduces long-term outdoor damage in days or weeks
- Fluorescent UV lamps recreate sunlight; condensation and water spray systems simulate rain and dew
- Precise temperature control throughout testing cycles
- Typical cycle: high-temperature UV exposure followed by dark, humid condensation at 100% relative humidity
- Ideal for paint coatings, automotive parts, plastics, wood, adhesives, and anodized films
