How to choose a breathable meter? Product features of the air permeable

There are several aspects that need to be paid attention to when purchasing a breathable instrument:

1. Meet the standards; It is particularly important to choose what standards the air permeable instrument meets, whether it meets the national standard or others.

2. Product after-sales; After all, what we are most afraid of is that there is such a small problem but there is no one to guide or repair, so the importance of after-sales is self-evident.

3. Cost-effective; When people buy things, they can't just pick the most expensive or the cheapest, but the most important thing is to choose the most suitable for themselves.

4. Company brand; The last thing to consider is the brand, after all, the product has strength, and the brand and reputation will not be too bad.

5. Product quality; After all, if you can't buy something back, there's a problem here.

The permeability of gas to materials is one of the important items for the testing of physical properties of materials, and materials with low permeability have certain barrier properties to gases. Materials with high permeability are relative to materials with certain barrier properties, they have a very large gas transmission rate, a wide variety of materials, and a wide range of uses. The air permeability tester and air permeability tester are the relevant testing instruments.

Introduction to the Air Permeability Tester

The so-called gas permeability test of materials refers to the specific gas permeability test of materials with certain gas barrier properties. As the name suggests, the gas permeability tester is a professional testing instrument that is professionally used for the gas permeability testing of these barrier performance materials. The air permeability tester is mainly used to test such barrier performance materials, which are mostly polymers or multi-layer composites made of polymers.

At present, the air permeability tester can be mainly divided into two types of test principle instruments: differential pressure method and isobaric method. Among them, the differential pressure method is widely used, and the differential pressure method air permeability tester can detect a wide range of test gases.

Introduction to the air permeability tester

The air permeability tester is mainly a professional testing instrument used to detect materials with large gas permeability, and the detection of gas permeability of this kind of material is called gas permeability test. For foam, leather, textiles, paper, cardboard, porous ceramics and other materials with high air permeability, the air permeability tester is very suitable. For specific applications, it is necessary to quantify the permeability of gases to these materials, and the permeability test of materials is an important means of monitoring.

For example, the proper selection of the air permeability of cigarette paper directly affects the appearance of cigarettes, the smell of cigarettes and the content of smoke components. The control of the breathability of textiles is a key factor that directly affects the wearing comfort of clothing.
