The air permeability tester (Gelley method) is a Gelley type air permeability tester that evaluates the air permeability of paper and cardboard and the breathability of wool fabrics based on the measurement method of the Geller testing machine. The air in the inner cylinder is compressed by weight, and a certain amount of air passes through the specimen that is fixed on the splint, and the time necessary for it is determined. There are two types of measurement methods: manual stopwatch measurement and automatic timer measurement method.

A separator is a thin film used to separate the positive and negative poles during an electrolytic reaction to prevent energy loss from direct reaction in the electrolytic cell.
Wang Yan type air permeability tester, also known as a gas permeability meter, is the flow of tiny air on a sheet of material in a laboratory environment,1At a pressure of 21kPa, the time required for 100ml of test gas to pass through a specific area of battery separator is recorded, and the air permeability is calculated. It is professionally suitable for the gas permeability test of battery separators, breathable films and related polymer materials, and is also suitable for the gas permeability test of cigarette paper and various papers.
The diaphragm permeability tester independently developed by Jinan Saicheng is mainly based on the test principle of the differential pressure method and follows the following standards:
