GPT-203 Differential Pressure Gas Permeameter Introduction: The GPT-203 pressure difference gas permeability tester is based on the testing principle of pressure difference method. It is a professional gas permeability tester used for thin film samples, suitable for measuring the gas permeability and gas permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at various temperatures. Features: 1. It is possible to simultaneously measure the gas permeability and gas permeability coefficient of the sample 2. Capable of completely independent testing of three test chambers 3. Wide range and high-precision temperature and humidity control to meet various testing conditions 4. Provide three test process judgment modes: proportional, fuzzy, and time modes 5. The testing range can be expanded as needed to meet the requirements of high transmittance testing 6. Support testing of toxic and flammable and explosive gases (customization required) 7. Using pneumatic clamping for the sample, convenient and fast 8. The system adopts electronic intelligent control, and the entire experimental process is automatically completed 9. Provide standard film for rapid calibration to ensure the accuracy of testing data 10. The product complies with GMP multi-level permissions 11. Micro printer, note printing of test statistics results at any time 12. Specialized computer communication software for real-time display of experiments, data analysis and processing, and data storage 13. Equipped with a USB universal data interface for convenient data transfer Technical parameters: Test range: 0.1~10000 cm3/m2 • 24h • 0.1MPa (conventional) Upper limit not less than 60000 cm3/m2 • 24h • 0.1MPa (expansion volume) Sample quantity: 3 pieces (data independent) Vacuum resolution: 0.05 Pa Vacuum degree of test chamber:<10 Pa Temperature control range: 10~60 ° C Temperature control accuracy: ± 0.1 ° C Sample size: Φ 95 mm Transmission area: 33.18 cm2 Test gas: O2, N2, CO2 and other gases (provided by the gas source user) Test pressure: 0.005 MPa~0.26 MPa Interface size: Ф 6mm polyurethane pipe Boundary dimension: 600 mm (L) × 475 mm (W) × 450 mm (H) Power supply: AC 220V 50Hz Net weight: 75 kg
