1.1 Equipment use
It is suitable for the determination of water vapor transmission rate of plastic film, composite film and other films and sheet materials. Through the determination of the water vapor transmission rate, the technical indicators of the control and adjustment of packaging materials and other products can be achieved to meet the different needs of product applications.
1.2 Equipment characteristics
Three cavities can simultaneously measure the water vapor transmission rate of the sample
The three tests are completely independent, and can test three same or different samples at the same time
Wide-range, high-precision temperature and humidity control to meet various test conditions
The system adopts computer control and the whole test process is completed automatically
Multiple test process judgment modes such as standard mode, proportional mode, continuous mode, etc.
Equipped with USB universal data interface to facilitate data transfer
1.3 Test principle
Clamp the pre-processed sample between the test chambers. Nitrogen with a certain relative humidity flows on one side of the film, and dry nitrogen flows on the other side of the film. Due to the presence of a humidity gradient, water vapor will pass through the high humidity side. Diffusion through the film to the low humidity side. On the low humidity side, the permeated water vapor is carried by the flowing dry nitrogen to the sensor. When entering the sensor, the same proportion of electrical signals will be generated. The electrical signals of the sensor are analyzed and calculated to obtain the sample’s value. Parameters such as water vapor transmission rate.
