WPT-204 Water Vapor Permeability Tester Introduction: The WPT-204 Water Vapor Transmittance Tester is based on the principle of infrared testing, providing a wide range and high efficiency water vapor transmittance detection for medium and high barrier materials. It is suitable for measuring the water vapor transmittance of plastic films, composite films and other films, sheet materials, and various high barrier materials in the fields of medical and building materials. Features: 1. High precision infrared moisture sensor improves the accuracy and stability of testing 2. High definition LCD touch screen, more intuitive content and easier operation 3. The four test chambers are completely independent and can simultaneously test four identical or different samples 4. A test chamber is used as a reference chamber to determine whether the test standard membrane data is accurate 5. Three test chambers are used to test samples, ensuring that three parallel samples can be tested at once 6. Wide range, high-precision, automated temperature and humidity control to meet various testing conditions 7. Unique testing structure, with four chambers tested at the same temperature and humidity, ensuring consistency in testing conditions for different chambers 8. The experimental results support multi format storage and data output, including experimental report Excel and cloud sharing 9. The product complies with GMP user multi-level permissions 10. Single and group statistical analysis of test results can be conducted 11. Equipped with ISP online control and upgrade functions, and can remotely change the testing function according to requirements 12. Specialized computer communication software for real-time display of experiments, data analysis and processing, and data storage Technical parameters: Test range: 0.01~60 g/m2 • 24h (conventional) Test accuracy: 0.01 g/m2 • 24h System resolution: 0.001 g/m2 • 24h Sample quantity: 1-4 pieces (data independent) Test temperature: 10~60 ° C (conventional) Temperature control accuracy: ± 0.5 ° C Test humidity: 0%, 35~90% RH Humidity control accuracy: ± 1% RH Test area: 50 cm2 Sample thickness: ≤ 3 mm (other thickness requirements can be customized) Carrier gas flow rate: 0~200 ml/min Test pressure: ≥ 0.20 MPa Interface size: 1/8-inch metal pipe Boundary dimension: 440 mm (L) × 450 mm (W) × 450 mm (H) Power supply: AC 220V 50Hz Net weight: 42 kg
