Water Vapor Transmission Rate Tester (Infrared sensor)
WVTR-I3
WVTR-I3 Water Vapor Transmission Rate Tester is designed and manufactured based on the infrared sensor method, used to measure the water vapor transmission rate of barrier materials with high and medium moisture barrier properties with a wide testing range and high testing efficiency. WVTR-I3 Water Vapor Permeability Tester is applicable to determination of water vapor permeability of plastic films, laminated film, high barrier materials, back sheet, sheeting, paper, sheet metal, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, consumer goods, photovoltaic and electronic industries, etc. It can also be extended to test the water vapor permeability test of bottles, bags, tubes and other containers.

Test Principle
The test specimen is mounted in the diffusion cell, which is 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.
