FAQ
1. What makes SUNTEST XXL+ suitable for high-volume flat and 3D sample testing?
The SUNTEST XXL+ provides a 3000 cm² horizontal exposure area, ideal for testing multiple flat or 3D samples simultaneously. It combines uniform irradiance, accurate BST and chamber temperature control, and realistic daylight simulation, enabling high-volume, reproducible, and accelerated weathering tests for industrial-scale applications.
2. How is temperature controlled in the chamber?
The chamber allows direct control of internal temperature up to 70 °C and optional Black Standard Temperature (BST) up to 100 °C. Temperature can be controlled either independently or in dual mode, using fans to regulate the temperature difference between the chamber and BST, ensuring precise and repeatable testing conditions.
3. Can the SUNTEST XXL+ simulate sunlight filtered through windows?
Yes. Optional optical filters allow the simulation of sunlight passing through window glass or other materials, while maintaining realistic irradiance and BST control. This feature ensures accurate testing of products exposed to natural or modified daylight conditions.
