Test Principle
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 electrolytic 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.

Test Standards
This test instrument conforms to the following standards: ISO 15106-3, GB/T 21529, DIN 53122-2, YBB00092003

Basic Application
Films :Plastic films, paper-plastic composite films, coextruded films, aluminum foils, aluminum composite films, glass fiber aluminum foil composite films and many others.
Sheeting :PP, PVC and PVDC sheets, metal foils, rubber pads, silicon wafers and other sheeting materials.
Packages :Plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g. plastic bottles, pouches, coated paper cartons, vacuum bags, metal three-piece cans, plastic packages for cosmetics, soft tubes for tooth paste, jelly and yogurt cups.

Extended Applications
Closure Systems :Water vapor barrier property of various closure systems for bottles, cartons and pouches.
Solar Back-sheets :Water vapor permeability test of solar back-sheets
Plastic Tubes :Water vapor permeability test of various sorts of tubes e.g. cosmetic tubes
Blister Packs :Water vapor transmission rate of whole blister packs
Aseptic Wound Protecting Films and Medical Plaster Patches :Test water vapor transmission rate of aseptic wound protecting films, medical plaster patches and other materials
Fuel Tanks of Cars :Plastic fuel tanks are widely used in cars for its light weight, buffering vibration and easy molding characters. But its fuel permeability is the most essential factor. This instrument can be used to test permeability of plastic fuel tanks
Battery Plastic Shell :Battery electrolyte is protected by the plastic shell from outside environment. Battery service life is directly depended on its water vapor permeability. This instrument can be used to test water vapor transmission rate of battery plastic shell
Paper Cups and Bowls :Test water vapor transmission rate of the whole packages for instant noodles and disposable paper cups

Features
Professional
