Main purpose:
Used for testing the air permeability of cigarette paper/battery separator/exchange membrane/charcoal paper/textile clothing/paper, etc., suitable for testing institutions and production enterprises to test the air permeability index.
Instrument technical specifications:
1. Differential pressure measurement range: 0~2000Pa, relative error not exceeding 2% (customizable);
2. Flow measurement range: 0~30L/min, relative error not exceeding 5% (customizable);
3. Display operation: large screen display, touch screen operation;
4. Sample gripper: 2.00cm ² gripper, 0.3cm ² gripper, 6.45cm ² gripper (customized according to requirements);
5. Print output: Micro printers directly print test data;
6. Test results: mean, standard deviation;
7. Gas: Compressed air;
8. Method A: Stabilize the airflow passing vertically through the sample at a constant flow rate, measure the pressure difference formed on both sides of the sample under this condition, and calculate parameters such as air flow resistance
Method B: By adjusting to create a constant pressure difference on both sides of the sample, measure the airflow rate passing vertically through a given area of the sample for a certain period of time, and calculate parameters such as air permeability.
9. Power supply: 220V, 50Hz.
Applicable standards: (customized according to applicable standards)
