Description
Product Introduction:
Used for testing the thermal and moisture resistance of textiles, including multi-layer fabric assemblies, as well as apparel and bedding.
Reference standard:
Standards such as GBT 11048, ISO 11092 (E), and ASTM F1868.
Product Features:
1. Test method: Method A—evaporative heating plate method (fabricated from a specialized material, replacing the conventional porous‑plate design);
2. Highly realistic skin with a sweating effect;
3. Control Operation: Large-color touchscreen with a menu-driven interface in both Chinese and English.
4. The inner liner of the atmospheric chamber is made of high-quality 316 stainless steel.
5. The atmospheric chamber employs a YM-channel system to precisely regulate temperature and humidity.
6. Water Level System: The water supply unit of the test sample is controlled by a dedicated chip, with a water level accuracy of up to 0.1 mm.
7. Electrically controlled lifting of the test bench, with a lifting range of 0–70 mm;
8. Equipped with a dedicated air duct to regulate the wind speed on the surface of the variable-frequency control experimental platform.
9. All instruments equipped with water‑related components are fitted with water‑level indicators and water‑level control valves, providing water‑level protection.
10. The indoor environment is equipped with fluorescent lighting, facilitating observation of the test specimens.
11. High-quality casters imported from South Korea, offering easy mobility and adjustable height; height adjustment range: 0–8 mm.
12. Equipped with a microcomputer control system and a data processor, it can directly measure and calculate the various performance parameters of the specimen.
13. The experimental chamber is wrapped with imported thermal insulation cotton on all sides to minimize environmental interference.
14. Equipped with imported temperature and humidity sensors to accurately measure the actual temperature and humidity within the test chamber.
15. All water‑carrying pipelines within the instrument are made of Taiwan‑manufactured engineering plastic tubing, with a service life of ten years.
