working principle
By using the principle of differential pressure method, the pre-processed sample is placed between the upper and lower measuring surfaces and a constant differential pressure is formed on both sides of the sample. Under the action of differential pressure, gas flows through the sample from the high-pressure side to the low-pressure side. According to the area, differential pressure and flow rate of the sample, the permeability of the sample is calculated.

Product features
(1) the chip and sensor of the instrument are imported from the United States, the test results are accurate, good repeatability, high precision.
(2) exquisite design: the instrument USES microcomputer technology, the test process is fully automated, fast and accurate.Touch screen LCD display results, and has data recording and processing functions, with print output.
(3) superior performance: compared with the traditional air permeability meter, the instrument has a high advantage, on the air permeability of the lower paper, can set a higher pressure difference, and on the air permeability of the higher paper can set a lower pressure difference, easy and accurate measurement results.
(4) easy to use, high automation: the traditional breathability tester test is not only slow and laborious, on the contrary, the breathability tester test is automatic and fast, at the same time, the accuracy of the test results are therefore guaranteed.Misoperation or low reproducibility of test results, problems caused by poor instrument design and manufacturing techniques, are effectively avoided in this instrument.
- Wide range: the instrument has three models (A, B, C), its range covers all paper permeability test.Type A is often used for wrapping paper and cultural paper (such as paper bag paper, filter paper, thermal paper, etc.), type B is often used for tobacco industry paper (such as cigarette paper, packaging paper, stripe paper, etc.), and type C is often used for punching paper (such as molding paper, tea filter paper).
