Electrolytic Method Water Vapor Permeability Analyzer W203 2.0 Introduction Based on the Electrolytic testing principle, this product is developed, designed, and manufactured in accordance with standards such as GB/T 21529 and ISO 15106-3. It is used to measure the water vapor transmission rate (WVTR) of samples under specified temperature and humidity conditions. The instrument is suitable for testing the water vapor barrier properties of high-barrier materials used in sectors including LCD display devices, solar cells, chip packaging, pharmaceuticals, and food products. Test principle The W203 2.0 Water Vapor Transmission Rate Tester operates on the electrolytic principle. A preconditioned specimen is secured within the test chamber, dividing it into a high-humidity side and a Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

low-humidity side. Humidified nitrogen flows along one side of the film, while dry nitrogen (carrier gas) flows at a constant rate along the other. Due to the humidity gradient, water vapor permeates from the high-humidity side to the low-humidity side. The water vapor that passes through the specimen is carried by the flowing dry nitrogen to an electrolytic sensor; by analyzing the electrical signals output by the sensor, parameters such as the specimen's water vapor transmission rate are determined.
