1. Utilising xenon arc lamps capable of simulating the full solar spectrum to reproduce destructive light waves present in diverse environments, these systems provide corresponding environmental simulation and accelerated testing for scientific research, product development, and quality control.
2. The DHX series xenon arc lamp test chambers are suitable for selecting new materials, modifying existing materials, or assessing changes in durability following alterations to material composition. They effectively simulate alterations occurring when materials are exposed to sunlight under varying environmental conditions.
3. Accelerated ageing tests are conducted by exposing material specimens to the light and thermal radiation of xenon arc lamps. This evaluates the lightfastness and weather resistance of certain materials under high-temperature light sources. Primarily used for automotive components, coatings, rubber, plastics, pigments, adhesives, textiles, and similar materials.
1. Imported colour touchscreen control system, delivering precise temperature regulation with high sensitivity;
2. High-temperature resistant, high-expansion sealing strips, tested over ten thousand cycles, exhibit robust elasticity and maintain shape integrity, ensuring chamber airtightness;
3. Turntable utilises an extra-long shaft motor, constructed from high-temperature resistant stainless steel to guarantee dimensional stability, uniform rotation, and even heating of test specimens;
4. Specimen racks constructed from high-strength stainless steel, facilitating easy cleaning without affecting chamber temperature during testing;
5. Standard test port (50mm) for convenient connection of test power cables or signal lines;
6. The observation window employs multi-layered hollow tempered glass, ensuring safe operation during testing;
7. For ease of movement, the unit incorporates PU swivel castors with locking feet, facilitating both mobility and secure positioning;
8. The modular control system incorporates an alarm system, phase failure protection, and earth leakage protection, delivering truly worry-free testing.
