W203 2.0 Electrolytic Method Water Vapor Transmission Rate Tester
Product introduction
This product is based on the testing principle of electrolysis method and is developed, designed and manufactured in accordance with GB/T 21529, ISO15106-3 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 Permeability Analyzer uses the principle of electrolytic method. The pre-treated sample is fixed in the middle of the test chamber, and the test chamber is divided into high humidity side and low wet side. Compressed air flows on one side of the film and dry nitrogen (carrier gas) flows at a fixed flow rate on the other side. Due to the presence of a humidity gradient, water vapor penetrates from the high-humidity side to the low-humidity side, and the water vapor through the sample is carried to the electrolytic sensor by flowing dry nitrogen. Parameters such as the water vapor transmittance of the sample are obtained from the electrical signal output by the sensor.
