FAQ
1. What is this product?
It is a precision physical laboratory instrument specifically designed to quantitatively measure the ability of air to pass through fabrics or porous materials.
2. What is this product used for?
It helps you quantify a fabric’s “breathability.” Through air permeability values, you can directly determine whether a fabric feels stuffy or cool, or evaluate the filtration resistance of industrial filter materials.
3. How does this product work?
The instrument uses a fan to create a specific pressure difference across both sides of the sample. Sensors detect the airflow passing through this area and automatically convert it into air permeability.
4. Why is this product important?
Breathability directly determines clothing comfort. For masks and protective suits, breathability data is a critical indicator balancing safety protection and respiratory ease.
5. Which industries is this product suitable for?
It is suitable for textile printing and dyeing enterprises, apparel brand quality control departments, medical protective equipment manufacturers, automotive interior R&D centers, third-party testing institutions, and university research laboratories.
