TP-TQD03A Air Permeability Tester adopts new technology and cooperates with the most general test method to test the air permeability of paper, cardboard or other sheet objects. This instrument is a fully automated instrument controlled by a single-chip microcomputer. Its test method meets the requirements of various methods such as Schober, Bendtsen and Gurley. It is an advanced instrument for testing paper air permeability in the papermaking, packaging and cigarette industries in China, and its performance meets international standards .
Working Principle: Utilize the principle design of differential pressure method, put the pre-treated sample between the upper and lower measuring surfaces, A constant pressure difference is formed on both sides of the sample, and the gas passes through the sample from the high pressure side under the action of the pressure difference Flow to the low-pressure side, and calculate the air permeability of the sample according to the area, pressure difference and flow rate flowing through the sample.
Features
The chip and sensor of the instrument are all imported from the United States, with accurate test results, good repeatability and high precision.
Exquisite design: The instrument adopts microcomputer technology, and the testing process is fully automated, fast and accurate. touch screen liquid
Crystal display results, and has data recording and processing functions, with printout. 3. Superior performance: Compared with the traditional air permeability meter, this instrument has a high advantage. For paper with low air permeability, a higher pressure difference can be set, while for paper with higher air permeability, it can be set Set a lower differential pressure for easy and accurate measurement results. 4. Easy to use and high automation: The traditional air permeability tester is not only slow and laborious, but the test of the air permeability tester is automatic and fast, and the accuracy of the test results is also guaranteed. Misoperation or low reproducibility of test results, which are caused by poor instrument design and manufacturing techniques, are effectively avoided in this instrument. 5. Wide range of application: The instrument has three models (Type A, Type B, and Type C), and its range covers all paper air permeability tests. Among them, 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 paper in the tobacco industry (such as cigarette paper, tipping paper, striped paper, etc.), and type C is often used for Perforated paper (eg, molded paper, tea filter paper).
