Water vapor permeability tester W203H

water vapor transmission ratefor packagingfor film

The Water Vapor Permeability Tester W203H is manufactured based on the infrared sensor method and is applicable to test the water vapor transmission rate of medium and high barrier materials such as plastic films, composite films, sheets, papers, and other various materials.13-inch touchscreen tablet running on the Windows 10 operating system.This instrument is designed and manufactured according to the infrared sensor method and meets the requirements of ISO 15106-2 and ASTM F1249.High precision sensors ensure high accuracy and repeatability of the WVTR measurement system.Three diffusion cells are integrated into a single instrument and share the same temperature and humidity, ensuring consistent test conditions across all test cells.Three distinct or equivalent specimens can be tested individually, providing independent results in a single operation.Equipped with a dual-flow dry-wet humidity control system, it can achieve three-stage humidity control ranges: 0% RH, 35% to 90% RH, and 100% RH, with an accuracy of up to ±1% RH.The high-precision temperature control system can precisely regulate temperature within the range of 10°C to 60°C, with an accuracy of up to ±0.1°C.A reference film for fast calibration ensures accurate and universal test data (optional).The instrument is equipped with SAICHENG's latest operating software, featuring a user-friendly interface, intelligent data processing, strict user management, secure data storage, electronic signature, etc.Test Principle: The test specimen is mounted in the diffusion cell, which is divided into a dry chamber and a controlled humidity chamber. A flow of dry nitrogen sweeps the dry side of the specimen, while the dry nitrogen carries the water vapor permeating through the specimen from the controlled humidity chamber to an infrared sensor. This sensor generates proportional electrical signals based on the water vapor concentration. The water vapor transmission rate is determined by analyzing and calculating these electrical signals. For package samples, dry nitrogen flows inside the package, while humidified nitrogen flows outside.Test Standards: This test instrument conforms to many national and international standards: GB/T 26253, JIS K7129, YBB00092003-2015.Applications: Suitable for testing the water vapor transmission rate of various membrane materials, including plastic films, plastic composite films, paper-plastic composite films, geomembranes, co-extruded films, aluminum-coated films, aluminum foil, aluminum foil composite films, and waterproof breathable films. Suitable for testing the water vapor permeability of various engineering plastics, rubber, building materials (waterproofing materials for construction), insulation materials, and other sheet materials, such as PP sheets, PVC sheets, PVDC sheets, nylon sheets, etc. Suitable for testing the water vapor permeability of paper and paperboard. Suitable for testing the water vapor transmission rate of containers such as plastic bags, paper boxes, plastic bottles, infusion bags, and infusion bottles.Technical Specifications:Test Range (Film test): 0.001 ~ 50 g/m·24h (Standard), 0.002 ~ 100 g/m·24h (Optional)Test Range (Container test): 0.000005 ~ 0.25 g/(pkg·24h) (Standard), 0.00001 ~ 0.5 g/(pkg·24h) (Optional)Resolution: 0.0001 g/m·24hNumber of Specimen: 1 ~ 3 (Independent testing results)Temperature Range: 10°C ~ 60°C (Standard)Temperature Accuracy: ±0.1°CHumidity Range: 5%RH ~ 90%RH, 100%RHHumidity Accuracy: ±1%RHTest Area: 50 cmSample Thickness: ≤ 3 mm (Customization is available)Carrier Gas: 99.999% High-purity Nitrogen (outside of supply scope)Carrier Gas Pressure: ≥0.20 MPaPort Size: 1/8-inch Metal TubingInstrument Dimension: 580 mm (W) × 750 mm (D) × 460 mm (H)Power Supply: AC 100-240V 50/60Hz (can be changed to local requirement)Net Weight: 72 kgConfigurations: Instrument, Tablet, Professional Software, Network Cable, Diamond-shaped Sampler, 1/8-inch Metal Tubing, Vacuum Grease, Nitrogen Pressure Reducing Valve, Humidity Control System.
