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.
