Permeation and Barrier Testing Instruments for packages,China Labthink price supplier

Permeation and Barrier Testing Instruments for packages include Gas Permeability Tester,Water Permeability Tester and Air Permeability Tester.

Gas permeability in packaging industry is a measure of the ability of a barrier material to allow gases (O ₂ , N ₂ and CO ₂ etc.) to permeate through it in a specific time. It usually depends on the type of material, pressure, temperature and thickness of materials.

It has the following models:

i-GASTRA 7200 Gas Transmission Rate Tester
i-GASTRA 7210 Gas Permeability Tester
i-ORGAMATE 7810 Organic Gas Permeability Analyzer
i-GASMATE 7820 Mixed Gas Permeability Analyzer

Water vapor permeability is a measure of the passage of water vapor through a membrane. It is the rate of water vapor transmission per unit area per unit of vapor pressure differential under test conditions.
It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR).

It has following models:
i-HYDRO 7300 Moisture Vapor Transmission Rate Tester
i-HYDRO 7310 Water Vapor Permeation Analyzer
i-HYDRO 7400 Water Vapor Transmission Rate Tester

Air Permeability is the resistance of fabrics (woven, knitted and non woven textile materials) to the passage of air under constant preset air pressure. Air permeability is an important property of some textile materials. The air permeability is mainly dependent upon fabric's weight and construction (thickness and porosity).

It has following models:

i-OXTRA 7600 Oxygen Transmission Rate Tester
i-OXTRA 7700 Oxygen Permeability Tester
