use:
The SG461-III fabric air permeability meter is used to test various flat materials such as: technical textiles, fabrics, knitted fabrics, woven fabrics (including tightly coated fabrics), non-woven fabrics, high air permeability paper, papermaking felt, glass fiber, The air permeability of air filters, industrial filter cloth (filter paper) and other materials can be tested quickly and accurately.

Applicable standards:
GB/T5453 Textiles Determination of fabric breathability (Chinese standard)
GB/T13764 Test method for permeability of geotextile (Chinese standard)
GB/T 22819 Determination of Air Permeability of Highly Air Permeable Paper (Chinese Standard)
GB/T 30133 General technical specification for the surface layer of sanitary napkins (Chinese standard)
GB/T 6719 Technical requirements for bag filter
FZ/T 64055 Needle-punched non-woven filter material for bag dust removal
ASTM D737, ISO9237, ISO5636, ISO7231, AFNORG07-111, BS5636, DIN53887, JISL1096-A and other national standards.


Instrument features:
1. Using microcomputer control system, high-precision pressure sensor, digital feedback to adjust the air suction volume, automatic tracking measurement and display of the pressure difference at each point, the same sample test multiple times and the stability is very good.
2. The instrument table has been treated with multiple paint and frosting, making the table silky smooth.
3. It can accurately detect the air permeability of various samples, with small table difference and high accuracy.
4. The operation is simple and the test time is greatly shortened.
5. Chinese LCD touch screen control, built-in 26-key Chinese and English input method, Chinese + Pinyin input is more intuitive.
6. Contains 11 test nozzles, 6 sets of indenter ferrules and fixed value rings, and a 8.5mm standard calibration orifice plate. All nozzles are calibrated point by point in the full range to ensure the accuracy of the test data. After comparison, the accuracy of the test results is comparable to that of imported instruments.
7. Data port: You can connect an external memory card to export data without worrying about data loss.
8. The test data is directly displayed on the LCD touch screen, and the setting values can be displayed without manual check-up calculations, which improves the test efficiency and meets various test standards in many countries. The test results are freely converted (mm/s, cfm, cm³) /cm²/s, L/m²/s, L/dm²/min, m³/m²/min, m³/m²/h, dm³/s at 25cm², etc.).
9. It is calibrated by a domestic standard orifice plate for measuring air permeability.

technical parameter:
1. Test range: 0.2-11838mm/s
2. Measuring unit: mm/s, cfm, cm³/cm²/s, L/m²/s, L/dm²/min, m³/m²/min, m³/m²/h, dm³/s at 25cm², etc.
3. Measuring time: 2-15 seconds, the actual test time depends on the sample
