Paper Air Permeability Tester

Introduction：

It uses new technology to test the breathability of paper, board or other sheet materials with the most common test methods.This instrument is a single chip microcomputer control, fully automated instrument.Its test methods meet the requirements of various methods such as schauber, bentsen, and gelai, etc. It is an advanced instrument to test the permeability of paper in the papermaking, packaging and cigarette industry in China, and its performance reaches the international standard.

Standards:

GB/T458、ISO5636/2、ISO5636/3、ISO5636/5、QB/T1667、GB/T22819、GB/T23227、ISO2965、YC/T172、GB/T12655

Working Principle:

Based on the principle design of differential pressure method, the preprocessed 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 effect of differential pressure, the gas flows from the high-pressure side to the low-pressure side through the sample. The permeability of the sample is calculated according to the area, differential pressure and flow through the sample.Or a constant airflow is formed on both sides of the sample, the pressure difference between the two sides of the sample is recorded, and the permeability of the sample is calculated.

Specifications：

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.

(5). 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).
