Battery Separator Air Permeability Tester

Battery Separator Air Permeability TesterPAPT-B01adopts the Gurley method test principle and is professionally suitable for testing the gas permeability and barrier properties of various materials such as battery separators, breathable membranes, and related polymer materials.

Test Principle:

Under standard temperature and humidity conditions and atmospheric pressure, the tester applies a pressure of 1.21 kPa to measure the time required for 100 mL of air to pass through a separator with an area of 6.45 cm².

Technical Advantages:

● Three test methods available: Gurley method, Schopper method, and Bendtsen method.

● The instrument's pressure difference is adjustable in the range of 0-3 kPa with an accuracy of 0.01 kPa, fully meeting the test pressure difference requirements of all three methods. The instrument features an extra-large test volume of 1 L, fully satisfying the volume requirements of all three methods.

● Achieves free conversion between test areas of 10.0 cm² and 6.42 cm² by adding a mask.

● The instrument is equipped with built-in temperature and humidity sensors for real-time monitoring of the test chamber's conditions.

● The instrument has excellent sealing performance, with air leakage not exceeding 1.0 ml/h.

● Dual-mode control (PC software optional).
