ASTM3574 Sponge Air Permeability Tester
sponge air permeability tester (sponge air permeability meter) is suitable for testing the air permeability of various polyether, polyvinyl alcohol and polyurethane sponge materials for rapid and accurate testing.
ASTM D3574-2008 "Test of Mechanical Properties of Polyurethane Sponge" (American Standard), ISO7231
1. It adopts 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 has good repeatability and stability.
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 nozzles for testing, 1 custom-made 25㎝² area test sponge fixture, and 1 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 the various test standards of many countries. The test results are freely converted (dm³/s at 25cm², m³ /min at 25㎝², mm/s, cfm, cm³/cm²/s, L/m²/s, L/dm²/min, m³/m²/min, m³/m²/h, etc.).
9. The instrument comes with a micro printer to print reports quickly and easily.
1. Test range: 0.2-11838mm/s
2. Measuring unit: dm³/s at 25cm², m³/min at 25㎝², mm/s, cfm, cm³/cm²/s, L/m²/s, L/dm²/min, m³/m²/min, m³ /m²/h etc.
3. Measuring time: 2-15 seconds, the actual test time depends on the sample
4. Measurement method: automatic constant pressure
5. Test accuracy: ≤±2%
6. Test pressure: 0-500pa (pressure difference on sample surface), 0-5000pa (pressure difference on nozzle surface)
7. Test area: 25㎝²
