Labthink Introduces PERME W3/330 Water Vapor Transmission Rate Test System

Aug. 28, 2009 - PRLog -- Labthink introduces PERME W3/330 Water Vapor Transmission Rate Test System, which is applicable in water vapor transmission rate tests for plastic film, laminated film, and flat sheet materials, as well as the finished package made from plastic, rubber, paper, glass, metal and other materials. By measuring the water vapor transmission rate, users can adjust and control the technical index of the packaging materials and other products, to meet the different requirements of application. This test system complies with ISO 15106-3, GB/T 21529, DIN 53122-2, YBB 00092003 and many other international standards.
This test system has many outstanding characteristics: 3 independent testing cells can give 3 results respectively, and can be connected together to enlarge the testing area for higher barrier materials. Its master base and satellite modules have the same testing functions. Therefore, 1 master base can support 9 satellite modules, 30 different samples can be tested together. As to test objects, flat film, sheets and finished packages can be tested.
The testing principle of this test system is as follows: Mount the preconditioned specimen between the testing cells, clamp tightly. Nitrogen with constant humidity flows through one side of specimen, dry nitrogen flows through another side of the specimen. Under the function of humidity difference/grades, water vapor passes through the specimen and enters the lower humid side, and is carried to the sensor by the dry nitrogen. The electrical signals are generated at the sensor when the water vapor enter,.   Calculate the water vapor transmission rate by analyzing the electrical signals. For package test, dry nitrogen flows in the package, humid nitrogen flows around the outer side of the package.
