Instrument Details
Instrument/Facility Name: Water Vapour Permeability Tester
Make                                   : Lab Think Instruments
Model                                  : TSY-W3
Specification   :This instrument determines water vapor transmission rate under temperature range of 5-95°C with resolution of 0.1ppm and has a test range of 0.001 ~ 50 g/m2·24h(under standard conditions) for samples with thickness < 1millimetre. The system is controlled by computer with LCD, menu interface and PVC operation panel, which could conveniently export test data, test results and test curves. Carrier gas of Nitrogen 99.999% high purity is used in the test. This test instrument conforms to the following standards: ISO 15106-3, GB/T 21529, DIN 53122-2, YBB 00092003

  Working Principles
Click to ViewUnder a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen into the dry side and then is taken to the sensor, where proportional electric signals will be generated. The water vapor transmission rate and other parameters can be obtained by analyzing and calculating these electrical signals.
