W/031 water vapor transmission rate tester Introduction: The W/031 water vapor transmission rate tester is also called a moisture permeability tester. Based on the cup method test principle, it is a water vapor transmission rate tester for film samples. It is suitable for water vapor of various materials such as plastic film, composite film, sheet material and medical and building materials. Determination of transmittance. Through the measurement of water vapor transmission rate, the purpose of controlling and adjusting the technical indicators of materials is achieved, and the different needs of product applications are met. Features: 1. Weighing method test principle, batch weighing according to the standard requirements, the system automatically clears before each measurement to ensure the uniformity and accuracy of the data. 2. Single test can test three samples at the same time. The wetting cup lifting and weighing is controlled by micro motor, and the data is accurate and reliable. 3. The moisture-permeable cups can be independently tested, the test process does not interfere with each other, and the experimental results are displayed independently. 4. Standard purge wind speed, effectively prevent the formation of humidity gradient above the moisture permeable cup, and ensure the accuracy of the test. 5. Wide range, high precision, automatic temperature and humidity control to meet the test under various test conditions. 6. The system is controlled by microcomputer, and the whole test process is completed automatically. 7. The test results support multi-format storage and data output, including experimental reports EXCEL, cloud sharing. 8. The system automatically clears before weighing, guarantees the accuracy of each weighing, and supports wide range power access. 9. Provide standard weight quick calibration mode, and the weighing system guarantees the accuracy of the test data. 10. Equipped with USB universal data interface for easy data output and delivery. Technical Parameters: Test range: 0.01 ~ 10,000 g / m2 • 24h (conventional) Number of samples: 1 to 3 pieces (optional 1-6 pieces) Test accuracy: 0.01 g/m2•24h System resolution: 0.001g Test temperature: room temperature ~ 65 ° C (conventional) Temperature control accuracy: ±0.1 °C (conventional) Test humidity: 10% RH ~ 98% RH (standard 90% RH) Control humidity accuracy: ±1% RH Test area: 33 cm2 Sample thickness: ≤ 3 mm (other thickness requirements can be customized) Sample size: Φ74 mm Test chamber volume: 50 L Gas source: compressed air / dry nitrogen Air source pressure: 0.6 MPa Interface size: Φ6mm polyurethane tube Dimensions: 620 mm (L) × 620mm (W) × 570mm (H) Power supply: AC220V 50Hz Net weight: 97 kg
