In the field of new energy and packaging industry, the hydrogen barrier performance of materials directly affects the efficiency of fuel cells and the safety of food and pharmaceutical packaging. The hydrogen permeability tester imported by Ke Run Experimental Equipment adopts a composite detection principle of vacuum pressure difference method and gas chromatography method. Through a three chamber independent temperature control system and intelligent fully automatic operation mode, it achieves accurate measurement of multiple parameters for materials such as plastic film, composite membrane, proton exchange membrane, etc.

　　Analysis of core technological advantages

1Multi scenario adaptability

The device supports wide temperature range testing from -40 ℃ to 100 ℃, meeting the simulation requirements for low-temperature start-up and high-temperature working conditions of fuel cells. Circulating medium temperature control technology combined with independent sensors ensures the stability of the experimental environment.

2Intelligent data management

Built in data audit tracking system, which can be integrated with laboratory information management system (LIMS) to achieve automatic archiving and traceability of test results. The user permission hierarchical management function complies with GMP and other compliance requirements.

3Composite testing principle

By using the pressure difference method to establish a gas permeation gradient, combined with gas chromatography separation technology, the gas permeability, diffusion coefficient, and permeability coefficient are synchronously output to provide multidimensional data support for material research and development.

　　Industry application value

In the field of fuel cells, this instrument can quantify the hydrogen permeability of proton exchange membranes, helping to improve battery energy efficiency and safety; In the food packaging industry, its detection sensitivity accurate to 10 ^ -5 cm ³/(m ² · d · Pa) can effectively evaluate the hydrogen barrier performance of cling film. In addition, the research and development of materials such as rubber seals and high barrier pharmaceutical packaging rely on the testing data of this equipment.
