    Product Description

    W3/330 Water Vapor Transmission Rate Testing Machine  is based on the electrolytic sensor method, which are available for the WVTR test of flexible films, sheets, foils and packages. This equipment adopts Labtink patent design and can test 3 specimens with independent results.

    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.


    • ISO 15106-3, DIN 53122-2
    • Based on the electrolytic sensor method.
    • 3 distinct or equivalent specimens can be tested individually with independent test results at one operation.
    • The system can be easily connected to a maximum of 10 instruments to accomplish up to 30 tests at the same time.
    • Water vapor transmission rate and oxygen transmission rate can be obtained at one operation by working .
    • Wide range and high precision of temperature and humidity control to support various combinations of non-standard test conditions.
    • Standard, proportional and continuous testing modes facilitate to minimize errors caused by human factor during testing process.
    • Convenient fast-access calibration port for temperature and humidity.
    • Reference film for accurate calibration.
