Weighing Method Composite Packaging Materials Wvtr Water Vapor Transmission Rate Testing System China Factory

After-sales Service: Online Technical Support

Warranty: 12 Months

Test Method: Desiccant Method and Water Method

Standard: ASTM E96

Number of Specimens: 1~6

WVTR-W6 Composite Packaging Materials Wvtr Water Vapor Transmission Rate Testing System(Gravimetric Method)WVTR-W6 Weighing Method Composite Packaging Materials Wvtr Water Vapor Transmission Rate Testing System, based on the Gravimetric method, provide a wide range and high efficiency water vapor transmission rate testing experience for low, medium and high water vapor barrier materials. It is suitable for the measurement of water vapor transmission rate of various materials such as plastic film, composite film, medical treatment, construction, etc. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production.Product FeaturesAdvanced TechnologyDual test mode: Desiccant method and Water method Equipped with high-precision weighing system, which can improve the system sensitivity and stabilityA new generation of circular structure test chamber design, making the temperature and humidity distribution more uniformWide-range, high-precision, automatic temperature and humidity control, meet various test needs Standard air velocity prevents water vapor from condensing on top of test dishes, ensuring a constant humidity difference between the inside and outside of the test dishesSelf-developed periodically weighing method and auto zero before each weighing guarantee the accuracy and uniformity of the testing dataConvenient fast-access calibration ports for temperature and humidity calibration.Reference film or standard weight for fast and accurate calibrationPrecision mechanical design not only ensures the system's ultra-high precision, but also greatly improves the test efficiency.High-end Configuration11.6" tablet with intelligent data processing function for comfort and smooth operation feelingBased on the user-friendly Windows operating interface for easy operationThe test process is recorded automatically, which can realize process data reproductionPowerful curve chart analysis function, convenient for comparison test and analysisSaves test data in different formats for convenient data transferPowerful functions such as window display, curve overlay analysis, test report customization, original data export, printing, editable with Office software, etcEquipped with data traceability, which can realize functions such as multi-level authority management, audit tracking, electronic signatures, etc., which meets the GMP requirements (optional)Pubtester also provides professional customization services to meet users' personalized needs in fixtures, software, etc. Provide lifetime software free upgradeTest PrincipleBased on gravimetric determination method, under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.ApplicationsBasic applicationFilmPlastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminum coated films, aluminum foil composite films, glass fiber aluminum foil paper composite films and many other film materialsSheetingPP, PVC and PVDC sheeting, metal foils, rubber pads and other sheeting materialsTextiles and Non-wovenTextiles and non-woven fabrics such as diaper, sanitation products, etc.Paper and Paper BoardAluminum coated paper for cigarette, paper aluminum plastic composite film and other paper and paper boardsExtended applicationInverted Cup MethodMount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cups are requiredArtificial SkinArtificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance.
