SN-N01 differential pressure gas permeability tester for measuring gas transmission rate of plastic films, composite films and high barrier packaging materials. Suitable for O2, CO2 and N2 permeability testing.

Gas Permeability Tester：The high precision gas permeability tester is a sophisticated machine that checks how well gases like oxygen, carbon dioxide, and nitrogen can pass through packaging materials. It helps determine if the packaging acts as a strong barrier to these gases, which is crucial for keeping products fresh and safe.

Oxygen Transmission Rate Tester：Ensure the integrity of your packaging and materials with our state-of-the-art Oxygen Permeation Tester, engineered to deliver unmatched accuracy in measuring oxygen permeability across films, membranes, and barrier packaging.

The three chamber oxygen permeability tester can simultaneously detect three samples at a time, with higher detection efficiency. Oxygen permeability tester, also known as oxygen permeability meter, is suitable for testing the oxygen permeability performance of films, sheets, paper, packaging and related materials in the fields of food, medicine, medical equipment, daily chemical, photovoltaic electronics, etc. It provides a wide range and high efficiency oxygen permeability detection for high, medium and low oxygen barrier materials.

It is based on the testing principle of an infrared moisture sensor. The pre-treated sample is clamped between the test chambers. Nitrogen with a stable relative humidity flows on one side of the film, and dry nitrogen flows on the other side of the film. Due to the presence of a humidity difference, water vapor will diffuse through the film from the high-humidity side to the low-humidity side.

Based on the testing principle of the infrared moisture sensor, it provides high-precision and high-efficiency water vapor transmission rate testing for materials with high and medium gas barrier properties. It is suitable for the water vapor transmission rate testing of various film materials such as plastic films, paper-plastic composite films, co-extruded films, aluminized films, aluminum foil composite films, glass fiber aluminum foil paper composite films, etc. in fields such as food, pharmaceuticals, medical devices, daily chemicals, photovoltaics, electronics, etc.

Single-chamber WVTR Tester：The water vapor barrier tester is a precision instrument designed to measure the water vapor transmission rate (WVTR) of materials, based on the test principle of infrared method, evaluating their ability to block or allow moisture transfer. This water vapor permeation analyzer is critical for industries requiring strict control over moisture-sensitive products, such as food packaging, pharmaceuticals, electronics, and textiles.

Three-chamber WVTR Tester (infrared method).Water vapor transmission analyzer,based on the test principle of infrared moisture sensor, it provides high precision and high efficiency water vapor transmittance test for high and medium gas barrier materials.

A gas chromatograph is a tool for the separation and analysis of multi-component mixtures. It uses an inert gas as the mobile phase and adopts chromatographic column separation technology. When multiple substances to be analyzed enter the chromatographic column, due to the different distribution coefficients of each component in the chromatographic column, the flow rates of each component in the chromatographic column are different. After passing through a certain column length, the mixed components leave the chromatographic column separately and enter the detector.

A gas chromatograph is a tool for the separation and analysis of multi-component mixtures.Detectable substances: benzene, cyclohexanone, xylene, ethanol, ethylbenzene, isopropanol, propanol, butanol, ethyl acetate, isopropyl acetate, n-butanol, toluene, n-butyl acetate, phosmet, 4-methyl-2-pentanone, etc.

Gas Chromatograph:It is used to detect the solvent residue in packaging and printed products.A gas chromatograph is a tool for the separation and analysis of multi-component mixtures. It uses an inert gas as the mobile phase and adopts chromatographic column separation technology.

The integrated nitrogen, hydrogen and air (gas generator) unit is a compact combined instrument integrating a nitrogen generator, a hydrogen generator and an air generator. It has a compact structure and is easy to operate. It is equipped with multiple levels of protection devices and is suitable for providing stable, high-quality and safe gases for gas chromatographs.
