Product nameDiaphragm Air Permeability Tester

Product modelRH-TQG645

DownloadDiaphragm Air Permeability Testerdownload

 Introduction:

RH-TQG645 Diaphragm Air Permeability Tester is used for testing the air permeability of battery diaphragm, mica tape, breathable film, thin film, paper and other materials and related polymer products. It is a fully automated instrument controlled by a single chip microcomputer. The test method takes into account various methods such as Schopper method, Bentsen method and Gurely method etc.

Working Principle:

The time required for 100ml air to pass through the 6.45cm² sample (diaphragm) under the pressure of 1.21kpa in the temperature, humidity and atmospheric pressure environment.

 

 

Product Features:

1.     Using US computer chip and stepper motor, coupled with reasonable design precision machining, to ensure the equipment is of high accuracy and repeatability. The calibration of the pressure sensor and flow is traceable.

2.     The instrument uses microcomputer technology, the test process is fully automated, fast and accurate. Touch-screen display results, and data recording and processing functions, with printing output.

3.     This instrument has the high superiority. It can set the higher pressure difference for the paper with the lower permeability, and set the lower pressure difference for the paper with the higher permeability, easily and accurately measure the result.

4.     The test of the permeability tester is automatic and fast, and the accuracy of the test results is guaranteed. This instrument effectively avoids these problems such as mishandling or low reproduction rate of test results.
