This gas permeability tester can test the gas permeability, gas transmission rate (GTR), Solubility coefficient, diffusion coefficient of plastic films, composite films, high barrier materials, sheets and metal foils, by using the pressure-differential method, the test temperature is adjustable.
• The gas permeability and gas permeability coefficient of the sample can be measured simultaneously
• Fully independent testing of three test chambers
• Wide range and high-precision temperature and humidity control to meet the test under various test conditions
• Three test process judgment modes are provided, namely, proportion mode, fuzzy mode and time mode
• The test range can be expanded as required to meet the requirements of high transmittance test
• Support the test of toxic gas and flammable and explosive gas (to be customized)
Pneumatic clamping is adopted for sample, which is convenient and fast
• The system adopts electronic intelligent control, and the whole test process is completed automatically
• Provide standard membrane for rapid calibration to ensure the accuracy of test data
• The product complies with GMP multi-level authority
• Micro printer, note printing test statistical results at any time
• Special computer communication software, which can perform real-time display of test, data analysis and processing, and data storage
• Equipped with USB universal data interface for convenient data transfer
The instrument adopts the principle of differential pressure method, and places the pre processed sample between the upper and lower test chambers for clamping. First, vacuum the low pressure chamber (lower chamber), and then vacuum the whole system; When the specified vacuum degree is reached, close the lower test chamber, fill the high-pressure chamber (upper chamber) with test gas of a certain pressure, and ensure that a constant differential pressure (adjustable) is formed on both sides of the sample; In this way, the gas will permeate from the high pressure side to the low pressure side under the effect of the differential pressure gradient. Through the monitoring of the internal pressure of the low pressure side, various barrier parameters of the tested sample can be obtained.
