W203 2.0 Water Vapor Transmission Rate Tester Electrolytic Method | High Barrier Materials WVTR Testing Product Introduction W203 2.0 is developed based on the electrolytic test principle, designed and manufactured in accordance with GB/T 21529, ISO 15106-3 and other international standards. It tests water vapor transmission rate of samples under controlled temperature and humidity, widely used for high barrier materials in LCD, solar cells, chip packaging, pharmaceuticals, food and more. Get a Free Quote Today   Test Principle W203 2.0 adopts the electrolytic method. The pre-treated sample is fixed in the test chamber, separating it into wet and dry sides. Humidified nitrogen flows on one side of the film, while dry nitrogen (carrier gas) flows on the other side at a fixed rate. Due to humidity gradient, water vapor permeates from the wet side to the dry side, carried by dry nitrogen to the electrolytic sensor. The WVTR value is calculated from the electrical signal output by the sensor.   Compliant Standards 2025 Chinese Pharmacopoeia 4010 GB/T 21529-2008 ISO 15106-3 DIN 53122-2 YBB 00092003-2015 ASTM F3299 JIS K7129-3   Technical Specifications Item Value Test Range 0.001~40 g/(m²·24h) (Film & Sheet) Resolution 0.0001 g/(m²·24h) Temperature Range 15 ~ 45℃ Temperature Accuracy ±0.1℃ Humidity Range 5 ~ 90%RH Humidity Accuracy ±1%RH Test Area 50.24 cm² Sample Size Φ100 mm Test Chambers 3 channels (independent data)   Key Features High-sensitivity sensor for ultra-high barrier materials in electronics, photovoltaics, displays.

Product introduction The GTR-10H gas permeation analysis system consists of a differential pressure permeation device and a gas chromatograph. It can test and analyze the gas permeability of various single-component gases and mixed gases, and can accurately calculate the permeability, permeability coefficient and other parameters of each component gas. The test gas has a wide range of types and high accuracy, and is suitable for gas permeation testing in the fields of fuel cell proton exchange membrane gas permeability testing, hydrogen permeation of hydrogen storage materials, gas density of bipolar plate materials, and natural gas storage materials.   Test principle Place the processed sample between the high-pressure chamber and the low-pressure chamber, and the low-pressure chamber is connected to the gas chromatograph through a quantitative loop. At the set test temperature, use a vacuum pump to evacuate the gas system, and then add a certain pressure of test gas to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the action of the pressure gradient, the gas penetrates from the high-pressure chamber to the low-pressure chamber through the film. The system injects the gas that penetrates into the low-pressure chamber into the gas chromatography column and separates it into various components, and calculates the gas permeability, gas permeability coefficient and other barrier performance parameters of each component.   Standard GB/T 20042.3，GB/T 20042.6-2011，GB/T 1038.1-2022，ISO 15105-1   Specification Item Technical Parameters Test range 2.0×10-12~3.0×10-7 mol/(m2·s.Pa) Detection system Gas chromatography (GC), TCD detector Test gas Gases such as hydrogen, oxygen, nitrogen, carbon dioxide, carbon monoxide, methane, etc., single component or mixed component Gas pressure 0~300kPa Permeation module temperature control range 15~60℃ Temperature control accuracy ±0.1℃ Permeation area 50.24 cm2 Sample size Φ110 mm Sample thickness ≤2 mm Sample quantity 1 piece Power supply AC 220 V，50 Hz   Features Advanced gas chromatography analysis technology The instrument is equipped with an advanced gas chromatography analysis module and a new microcomputer temperature control system, which can achieve 16-step program temperature rise with high temperature control accuracy; it adopts multi-processor parallel working mode, and can be equipped with a variety of high-performance detectors.
