FAQ

1. What materials can be tested using the SUN-master Benchtop Xenon Arc Weathering Test Chamber?

The SUN-master is suitable for a wide range of materials including packaging materials, cosmetics and pharmaceutical packaging, printing inks, industrial textiles, surface films, agricultural chemicals, building sealants, and dental materials. Its design allows accelerated evaluation of light stability and weathering resistance across multiple industries, supporting both product development and quality control applications.

2. How does the SUN-master achieve accelerated aging of test samples?

The chamber exposes samples to light intensity equivalent to summer midday sunlight on a continuous basis, up to 24 hours per day. Combined with a xenon arc light source that closely simulates full-spectrum natural sunlight, this continuous exposure significantly accelerates aging processes such as color change and material degradation, while maintaining consistent and repeatable test conditions.

3. How is irradiance stability maintained during long-term testing?

The SUN-master uses an automatic irradiance control system with solar eye feedback. This system continuously monitors light output at specified wavelengths and compensates for changes caused by lamp aging or other factors. As a result, irradiance remains stable throughout the test, ensuring reliable and reproducible test results.

4. What temperature parameters can be controlled during testing?

The chamber allows direct setting and control of black panel temperature from 45 to 100 ℃ and black standard temperature from 45 to 95 ℃, both with an accuracy of ±2 ℃. Temperature control is achieved through a fan-assisted system, ensuring stable thermal conditions during exposure.
