Electrolytic Method Water Vapor Permeability Analyzer W203 2.0 Introduction This product is based on the testing principle of electrolysis method and is developed, designed and manufactured in accordance with ISO15106-3, GB/T 21529 and other standards. It is used to test the water vapor transmission rate (volume) of samples under set temperature and humidity conditions. It is suitable for testing the water vapor transmission performance of films, sheets, paper, packaging and various materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc. It is an ideal configuration instrument for offline or online testing of the barrier properties of packaging materials by production units in the packaging industry. Test principle W203 2.0 Water Vapor Transmission Rate Tester adopts the principle of Electrolysis. The pre-treated sample is fixed in the middle of the test chamber, and the test chamber is divided into a high humidity side and a low humidity side. Humidified nitrogen flows on one side of the film, and dry nitrogen (carrier gas) flows at a fixed retention rate on the other side. Due to the existence of humidity gradient, water vapor will penetrate from the high humidity side to the low humidity side. The water vapor that penetrates the sample is carried to the electrolytic sensor by the flowing dry Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

nitrogen. The water vapor transmission rate and other parameters of the sample are obtained through the electrical signal output by the sensor.
