Product Description ModelBZ-WVTR-204 StandardsISO 15106-2, ASTM F1249, GB/T 26253-2010, TAPPI T557, JIS K7129, YBB00092003-2015This water vapor transmittance testeris applicable to the measurement of water vapor transmittance of plastic film, composite film, sheet materials, building materials and other high barrier materials. Based on the principle of infrared method, features high efficiency and wide test range. Features High precision infrared moisture sensor improves the accuracy and stability of the test? High definition LCD touch screen, more intuitive content and easier operation? Each test chamber are completely independent, 1 or 3 identical or different samples can be tested at the same time? A test chamber is used as the reference chamber to determine whether the test standard membrane data is accurate? Wide range, high-precision, automatic temperature and humidity control to meet the test under various test conditions? Unique test structure, four chambers are tested at the same temperature and humidity to ensure the consistency of test conditions of different test chambers? Test results support multi format storage and data output, including experimental report Excel and cloud sharing? The product complies with the GMP user's multi-level permissions? Single and group statistical analysis of test results can be conducted? It has ISP online control and upgrade functions, and can change the test function remotely as required? Special computer communication software, which can perform real-time display of test, data analysis and processing, and data storagePrincipleThe test principle of infrared sensor method is adopted. The sample to be tested is clamped between the dry and wet chambers with constant temperature. There is a certain humidity difference on both sides of the sample. Due to the existence of humidity gradient, the water vapor will diffuse from the high humidity chamber to the low humidity chamber. In the low humidity chamber, the water vapor is carried to the infrared sensor by the carrier gas. When it enters the sensor, it will generate an electrical signal of the same proportion. Through the analysis and calculation of the electrical signal of the sensor, Thus, the water vapor transmission rate and moisture permeability coefficient of the sample can be obtained.Test materialsFilm Plastic film, plastic composite film, paper plastic composite film, geotechnical film, coextrusion film, aluminized film, aluminum foil, aluminum foil composite film, waterproof breathable film and other film materials Sheet Engineering plastics, rubber, building materials (waterproof materials for building), thermal insulation materials, such as PP sheet, PVC sheet, PVDC sheet, nylon sheet, etc Paper and cardboardPaper and paperboard SpecificationsModelBZ-WVTR-201BZ-WVTR-203Test scope0.01~50 g/m2 · 24h (normal sample)0.00005 ~ 0.25 g/(pkg·24h)( Packaging components)Test accuracy0.0001 g/m2·24hNumber of samples13Test temperature10~60 ° C (normal)control accuracy±0.1°CTest humidity0%RH,35%RH ~ 90%RH,100%RHHumidity control accuracy±1%RHTest area50 cm2Sample thickness≤ 3 mm (other thickness requirements can be customized)Test pressure≥0.20 MPaInterface size1/8 inch metal pipeOverall dimensions400 mm (L) × 600 mm (W) × 350 mm (H)600 mm (L) × 700 mm (W) × 450 mm (H)Power SupplyAC 220V 50HzNet weight30 kg60kgConfigurationsStandard configuration: host, professional software, communication cable, sampler, gloves, micro printerOptional parts: standard membrane and air compressorRemarks: The air inlet of this machine is 1/8 inch metal pipe; Gas source and distilled water provided by users Gurley method air resistance tester ISO 5636,TAPPI T460Company Profile
