C130H Gas Permeation Testing System - Plastic Film Breather - Differential Pressure Gas Permeation Instrument

Labthink C130H Gas Permeation Testing System - Plastic Film Breather - Differential Pressure Gas Permeation InstrumentBased on the principle of differential pressure testing, it is specialized in measuring the gas permeability, solubility coefficient, diffusion coefficient, and permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at various temperatures. Compliant with multiple testing standards such as GB, ISO, ASTM, etc.

Testing principle:

C130H adopts the principle of differential pressure testing, placing the pre processed sample between the upper and lower testing chambers, clamping it, first vacuuming the low-pressure chamber (lower chamber), and then vacuuming the entire system; After reaching the specified vacuum degree, close the lower chamber of the test, fill the high-pressure chamber (upper chamber) with a certain pressure of test gas, and ensure that a constant pressure difference (adjustable) is formed on both sides of the sample; In this way, gas will permeate from the high-pressure side to the low-pressure side under the action of pressure gradient. By monitoring and analyzing the pressure inside the low-pressure side, various barrier parameters of the tested sample can be obtained.

Reference standard:

ISO 15105-1、ISO 2556、GB/T 1038-2000、ASTM D1434、JIS K7126-1、YBB 00082003
