Breathability detector industry is also known as permeability meter, pressure difference method permeability meter, permeability meter, gas transmission rate tester, gas transmission rate meter. Permeability test refers to the barrier effect of packaging materials on gas and other permeates, and the permeability test is an important indicator of product shelf life analysis from the perspective of packaging. The gas permeability detector is suitable for the determination of gas permeability, solubility coefficient, diffusion coefficient and permeability coefficient of plastic film, composite film, high barrier material, sheet and metal foil at various temperatures.

Common name:

Breathability tester, pressure difference method breathability tester, breathability tester, gas permeability tester, gas permeability tester, gas permeability tester, gas permeability tester, pressure difference method breathability tester.

The air permeability tester industry is also known as the differential pressure method gas permeability meter. Permeability test refers to the barrier effect of packaging materials on gas and other permeates, and the permeability test is an important indicator of product shelf life analysis from the perspective of packaging.
The permeability tester is suitable for the determination of gas permeability, solubility coefficient, diffusion coefficient and permeability coefficient of plastic film, composite film, high barrier material, sheet and metal foil at various temperatures.
Test Principle

Place the pre-treated sample between the upper and lower test chambers and clamp it. First, vacuum the low-pressure chamber (lower chamber), then vacuum the whole system. When the specified vacuum degree is reached, close the test lower chamber, fill the high-pressure chamber (upper chamber) with partial pressure test gas, and ensure that a constant pressure difference (adjustable) is formed on both sides of the sample, in this way, the gas will penetrate from the high-pressure side to the low-pressure side under the action of the differential pressure gradient, and through the monitoring of the internal pressure of the low-pressure side, the barrier parameters of the measured sample are obtained.
