Infrared Method Water Vapor Permeability Analyzer W405L Introduction The Infrared Water Vapor Transmission Rate Analyzer W405L is a high-end precision packaging material testing instrument newly developed and upgraded by the GBPI R&D team based on ASTM and GB standard requirements and market demand. It is used to test the water vapor transmission rate (quantity) of samples under set temperature and humidity conditions. It is suitable for water vapor transmission performance testing of films, sheets, paper, packaging and various materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc. Test principle W405L Water Vapor Transmission Rate Tester adopts the infrared method principle. The pre-treated sample is fixed in the middle of the test chamber, and the test chamber is divided into a high humidity chamber and a low humidity chamber. Compressed air flows in the high humidity chamber, and dry nitrogen (carrier gas) flows in the low humidity chamber at a fixed flow rate. Due to the existence of humidity gradient, water vapor will penetrate from the high humidity chamber to Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

the low humidity chamber. The water vapor that penetrates the sample is carried to the infrared sensor by the flowing dry nitrogen. The water vapor transmission rate and other parameters of the sample are obtained through the electrical signal output by the sensor.
