Principle
Infrared detection sensor method is used by i-Hydro 7900 Water Vapor Transmission Rate Testing System. The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infrared sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package samples, dry nitrogen flows inside the package, and moisturized nitrogen flows outside.
Standards
This instrument conforms to the following standards:
ASTM F1249, ISO 15106-2, GB/T 26253-2010, TAPPI T557, JIS K7129
