Infrared Method Water Vapor Permeability Analyzer W416 2.0 Introduction The W416 2.0 Water Vapor Transmission Rate (WVTR) Tester, utilizing the infrared sensor method, is a high-end, precision instrument for testing packaging materials. Developed by the R&D team at Guangzhou Biaoji (GBPI), it is designed in accordance with standards such as GB/T 26253 and ASTM F1249, while also addressing specific market requirements. Based on the infrared moisturesensing principle, the instrument offers a wide measurement range and high efficiency for determining the water vapor transmission rate of materials with high, medium, or low barrier properties. It is suitable for evaluating the water vapor barrier performance of films, sheets, paper, finished packaging, and other related materials used in sectors including food, pharmaceuticals, medical devices, daily chemicals, and photovoltaic electronics. This instrument serves as an ideal solution for manufacturers in the packaging industry to conduct either offline or online testing of the barrier properties of their packaging materials. Test principle The W416 2.0 Water Vapor Transmission Rate Tester operates based on the infrared sensor method. A pre-conditioned specimen is secured within the test chamber, dividing it into a highhumidity side and a low-humidity side. Compressed air flows through the high-humidity side, while dry nitrogen (carrier gas) flows at a constant rate through the low-humidity side. Due to the humidity gradient, water vapor permeates from the high-humidity side to the low-humidity side. Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

The water vapor that passes through the specimen is carried by the flowing dry nitrogen to an infrared sensor; by analyzing the electrical signals output by the sensor, parameters such as the specimen's water vapor transmission rate are determined.
