With the development of oxygen micro detection, micro oxygen sensor is gradually used in the field of oxygen permeability of material, i.e., sensor method of gas permeability testing. Different gas sensors can be used to test the permeability of different gases. At present, testing technologies of oxygen and carbon dioxide permeability have . Amongst the methods of permeability measurements, the steady state method is widely used for high permeability measurement as it merely requires a stable fluid flow in the tested sample (Liu et al., 2018).But for materials with low permeability, this method is often unacceptable due to the high time consumption and thermal sensitivity of pressure and gas .China Gas permeability tester catalog of ISO2556 CE Differential Pressure Method Package Foil Barrier Materials Gas Permeability Analyzer for Lab Use, ASTM D1434 CE Films and Sheeting Barrier Materials O2, N2 and CO2 Gas Transmission Rate Tester provided by China manufacturer - Pubtester Instruments Co., Ltd., page1. .

In Table 4, there is no distinct relevance of the gas permeability and porosity of the testing samples; thus, fractal theory is applied to study the relationship between the pore size distribution .Klinkenberg (1941) reported a variation in the permeability test results with the pressure when gas is used as testing fluid. Klinkenberg found that for a given porous medium as the mean pressure increased the calculated permeability decreased. Mean pressure is defined as follow: This variation caused by “gas slippage” phenomenon.Labthink Gas Permeability Tester series is the most advanced and complete product line to test the Gas Transmission Rate (GTR) of packaging materials by differential pressure method and Oxygen Transmission Rate (OTR) by Coulometric Sensor Method.

Pure gas permeability results were obtained using the pressure-rise time-lag method [17–20]. Membranes were exposed to individual gases, like H 2, CH 4, and CO 2. In a typical experiment, both sides of the membrane are evacuated to an equal vacuum. The test cell is then isolated, and the pressure at zero time is used .
Gas Permeability tester involves measurement of flow rate of a fluid across a sample and the pressure drop across it in order to compute permeability using Darcy’s law. Gas flow rates and pressure drops are also used to compute many other useful characteristics of porous media. Measurement of flow rates of different gases can also permit pore . The two main numerical results are (1) the normalized apparent gas permeability k app /k 0 obeyed well defined power laws, k app /k 0 = w g (z-z c) β, where the prefactor w g and exponent β are functions of σ/ but do not depend on the type of lattice used, and (2) the scale-invariant parameters investigated (i.e., z-z c and σ/) have .We have designed our Coating Gas Permeability Tester to measure the degree of gas permeation through a coating due to the coating through porosity and other interconnected defects.
