W309 Weighing Method Water Vapor Transmittance Tester Introduction: The W309 water vapor permeability tester is based on the cup method testing principle and is a professional water vapor permeability tester used for thin film samples. It is suitable for measuring the water vapor permeability of various materials such as plastic films, composite films, sheet materials, medical and building materials fields. By measuring the water vapor transmission rate, the technical indicators for controlling and regulating materials can be achieved to meet the different needs of product applications. characteristic: The principle of weighing method testing is intermittent weighing that meets standard requirements. The system automatically resets before each measurement to ensure data consistency and accuracy 2 high-definition LCD touch screens, with more intuitive content and easier operation Three single tests were conducted on nine samples, with a fully automated process. The lifting and weighing of the moisture permeable cup were stably controlled by an electric cylinder, ensuring accurate and reliable data Four of the nine breathable cups can be independently tested without interfering with each other, and the test results are displayed independently 5 innovative cycle dehumidification systems effectively prevent the formation of humidity gradients above the moisture permeable cup, ensuring the accuracy of testing 6 wide range, high precision, automated temperature and humidity control to meet various testing conditions 7 adopts adjustable wind speed function to ensure fast and uniform humidity in the testing chamber 8. The experimental results support multi format storage and data output, including experimental report Excel and cloud sharing Adopting an automatic calibration weighing module, the weighing system ensures the accuracy of the detection data 10 products comply with GMP user multi-level permissions 11. Single and grouped statistical analysis of experimental results can be conducted 12 has ISP online control and upgrade functions, and can remotely change test functions according to requirements 13 specialized computer communication software, capable of real-time display of experiments, analysis and processing of data, and data storage Technical parameters: Test range: 0.1~10000 g/m2 • 24h (conventional) Sample quantity: 1 to 9 pieces (data independent of each other) System resolution: 0.0001 g Test temperature: 10 ° C~55 ° C (conventional) Temperature control accuracy: ± 0.1 ° C Test humidity: 10% RH~90% RH (relative humidity) Humidity control accuracy: ± 1% RH Blowing wind speed: 0.5~2.5 m/s (non-standard optional) Test area: 33.18 cm2 Sample thickness: ≤ 3 mm (other thickness requirements can be customized) Sample size: Φ 72 mm Interface size: 6 mm polyurethane pipe Dimensions: 650 mm (L) × 600 mm (W) × 420 mm (H) Power supply: AC 220V 50Hz Net weight: 50 kg
