C101B Gas Permeability Test System

C101B Gas Permeability Test System

Product catalog summary

Overview: The C101B Gas Permeability Test System is designed to measure the gas transmission rate of various materials such as plastic films, composite films, high barrier materials, sheets, and metal foils. It operates based on the differential pressure method and adheres to international standards including GB, ISO, and ASTM.

Features:

Tests permeability of various non-hazardous gases.
Supports temperature control for diverse testing conditions.
Automated processes for vacuumizing, pressure maintenance, and test initiation/completion.
Offers both automatic and manual test modes.
Includes a high-quality stainless steel test cell for enhanced sealing.
Equipped with an imported manual isolation valve for improved sealing and reduced failure rates.
Compact industrial computer design with fast cooling.
Reference film provided for quick calibration.
Operates independently with single-chip microcomputer control.
Test reports exportable in formats like EXCEL and PDF.
Optional micro printer for automatic test data printing.
RS232 data interface for computer connectivity, curve analysis, data storage, and report printing.

Test Principle: The specimen is placed in a test cell forming a sealed barrier between two chambers. The lower chamber is evacuated, followed by the entire cell. Gas is introduced into the higher-pressure chamber, creating a pressure difference. Gas permeates through the specimen, and permeability is determined by analyzing pressure changes in the lower chamber.

Standards: Conforms to ISO 15105-1, ISO 2556, GB/T 1038-2000, ASTM D1434, JIS K7126-1, YBB 00082003.

Applications:

Films: Tests gas transmission rates of various films including plastic, paper-plastic composite, coextruded, aluminized, and aluminum foil composite films.
Sheets: Tests gas transmission rates of materials like PP, PVC, PVDC sheets, metal foils, rubber pads, and silicon wafers.

Catalog excerpts

C101B Gas Permeability Test System C101B Gas Permeability Test System is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate of plastic films, composite films, high barrier materials, sheets, and metal foils at different temperatures. The test system conforms to GB, ISO, ASTM and other international standards. Features note1 • Applicable to testing the permeability of various gases (exclude flammable, explosive and other hazardous gases) • Support temperature control to satisfy tests under different conditions (optional) • The processes of vacuumizing, pressure maintaining, start test and end test are automated. • Automatic and manual test mode. • Built-in high-quality stainless steel test cell with better sealing performance. • Imported manual isolation valve is adopted for better sealing performance and lower failure rate • Industrial computer appearance design, small size and fast cooling • Reference film is provided for quick calibration • The system adopts single-chip microcomputer control and can run independently • The test report can be exported in common formats such as EXCEL and PDF • Support micro printer, automatically print test data (optional) • Equipped with RS232 data interface, which can be connected to computer software for curve analysis, data storage, report printing, etc. (optional) Test principle The pre-conditioned specimen is mounted in the test cell as to form a sealed barrier between two chambers. The lower-pressure chamber (lower chamber) is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber (upper chamber) and a constant pressure (adjustable) difference is generated between the two chambers. The gas permeates through the specimen from higher pressure side into the lower pressure side. The gas permeability of the specimen can be obtained by analyzing the pressure changes in the lower chamber.
