Product IntroductionPAPT-B02 Air Permeability Tester is used to test the air permeability of polymer materials, films, paper and paperboard by the Bendtsen method (Gurley or Schober methods optional).
Features- Three test methods available: Gurley, Schober and Bendtsen.
- Adjustable pressure difference 0–3 kPa with 0.01 kPa accuracy to meet requirements of all methods.
- 1 L test volume compliant with method requirements.
- Interchangeable masks for test areas 10.0 cm2 and 6.42 cm2.
- Built-in temperature and humidity sensor for real-time chamber monitoring.
- Leakage rate ≤ 1.0 ml/h.
- Dual-mode control (manual/electronic); computer software optional.

Testing Principle- Bendtsen: Under a constant pressure difference of 1.47 kPa, record the gas flow through the test surface after clamping for 5 seconds.
- Schober: Under a constant pressure difference of 1.00 kPa ±0.01 kPa or 2.50 ±0.01 kPa, select an appropriate test duration and measure the gas flow through the sample by the test volume.
- Gurley: Under a constant pressure difference of 1.23 kPa, measure the time taken for 100 ml of gas to pass through.
Test StandardISO 5356
Configuration- Standard configuration: Main instrument, power cord
