The TSY-W3 electrolytic water vapor permeability tester is applicable to testing of various packaging materials (such as plastic films, laminated films, etc) and many kinds of barrier materials in pharmaceutical industry Users can control and adjust the technical index by testing the water vapour transmission rate
In product application, it can satisfy different requirements of users.
The basic principle of operation is as follows.
Place the specimen between the separate dry and humid chambers: saturated water vapour will transmit through specimen from the upper chamber to the lower chamber and then be carried to the sensor, which generates a proportional electrical signal.
Determine the mass of water vapour transmission and water vapour transmission rate by analysis and calculations based on the sensor electrical signal.
