Gas Permeability Tester
Machine Features:-
Gas Permeability Tester applies to air
block and gas permeability test of all kinds of
flexible packaging materials such as films, foils,
complex films and other plastic filmy materials. It is
an indispensable testing instrument in packaging
material testing, choosing and researching work.

| 1. Characteristics |
Updated products with more accurate
test results and more flexible test model.
Three chambers combined, selectable random
groups for specimen.
Design in fashion, produced mainly with high-tech constructive materials.
More constant and steady test conditions caused by employing most-advanced anti-hot/humidity technologies.
Selectable and flexible test models according to experiences.
Two operating modes: manual or automatic.
Differential pressure principle as the most commonly used standard.
High accurate pressure sensor with high efficiency and precise date.
Testing results can be displayed through curve, clear at a glance with test temperature and humidity displayed
while in test.
Advanced test technologies which suit to the real produce and use conditions.
Completely and automatically controlled by computer with more friendly manipulation.
Powerful software with more functions.
Search and rectify errors automatically with temperature fluctuation resistance.
Conveniently store, search, print test documents, perfect content test report.
Powerful overload function, protected by both software and hardware.

| 2. Principle |
Keep certain pressure difference between two sides of the specimen under definite conditions of temperature and
humidity. Calculate the mass and rate of gas transmission by testing the change of pressure in the lower pressure
side.
|
| 3. Test procedure |
The relationship between pressure and time will be displayed on the screen of the computer in real time after test
is started and permeation time will be calculated automatically according to permeation ratio. Test will stop when
intervened by users or test results are up to the default. The system will decide whether to print test results or
operate other data process according to users’ requirements.
