Permeability tester N600E

gas permeabilityair permeabilityfor lithium battery

Introduction
Battery Diaphragm Gas Permeability Tester N600E is designed and developed according to GB/T 36363-2018 and related standards. It uses the differential pressure method for professional measurement of air permeability of battery separators, breathable membranes and related polymer materials.

Test principle
Under controlled test temperature, humidity and ambient pressure, the instrument applies 1.21 kPa and measures the time required for 100 mL of air to pass through a diaphragm with an area of 6.45 cm2.

Standards
ISO 5636-5, TAPPI T460, GB/T 36363
