DRK311 Water Vapor Transmission Rate Tester (Electrolysis Method)

DRK311 water vapor transmission rate tester (electrolytic method), the instrument is suitable for the determination of water vapor transmission rate of plastic films, composite films and other films and sheet materials. Through the measurement of water vapor transmission rate, the technical indicators of control and adjustment of packaging materials and other products can be achieved to meet the different needs of product applications.

Instrument characteristics:

1. Three chambers can simultaneously measure the water vapor transmission rate of the sample;

2. The three test chambers are completely independent and can test three identical or different samples at the same time;

3. Wide-range, high-precision temperature and humidity control, to meet the test under various test conditions;

4. The system adopts computer control, and the whole test process is completed automatically;

5. Equipped with USB universal data interface to facilitate data transfer;

6. The software follows the principle of GMP authority management, and has functions such as user management, authority management, and data audit tracking.

Test principle:

The pretreated sample is clamped 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. Diffusion through the film to the low-humidity side. On the low-humidity side, the permeated water vapor is carried to the sensor by the flowing dry nitrogen. When entering the sensor, an electrical signal of the same proportion will be generated. Through the analysis and calculation of the electrical signal of the sensor, the parameters such as water vapor transmission rate.
