YYP 121E Air Permeability Tester(cigarette papers,filter plug wrap and filter joiningpaper)

Instrument Introduction:

The permeability tester adopts new technology and is combined with the most common testing method to measure the permeability of paper, cardboard or other sheet-like objects. This instrument is a fully automated device controlled by a single-chip microcomputer. Its testing method meets the requirements of various methods such as Schöberl, Bentsen and Gellray, and is an advanced instrument for testing paper permeability in the papermaking, packaging and cigarette industries in China. Its performance meets international standards.

Working principle:

Based on the principle of the pressure difference method, the pre-treated sample is placed between the upper and lower measurement surfaces. A constant pressure difference is formed on both sides of the sample. Under the action of the pressure difference, the gas flows from the high-pressure side through the sample to the low-pressure side. The permeability of the sample can be calculated based on the area through which the gas flows, the pressure difference, and the flow rate.

Application scope

Paper, cardboard.

Product Function

Test of Air Permeability

Product features

The chips and sensors of this instrument are all imported from the United States. The test results are accurate, repeatable and of high precision.

The design is exquisite: This instrument adopts microcomputer technology and the testing process is fully automated, which is fast and accurate. The results are displayed on a touch screen liquid crystal display, and it also has data recording and processing functions, along with printing output.

 The performance is superior: Compared with traditional permeability meters, this instrument has great superiority. For paper with lower permeability, a higher pressure difference can be set, while for paper with higher permeability, a lower pressure difference can be set, making it easy and accurate to measure the results.

It is convenient to use and has high automation: When testing with traditional permeability meters, the process is not only slow but also laborious. In contrast, the testing of this permeability tester is automatic and fast, and the accuracy of the test results is thus guaranteed. Problems such as incorrect operation or low reproducibility of test results, which are caused by poor design and manufacturing technology of the instrument, have been effectively avoided in this instrument.
