| Basic application |
Film |
Water vapor transmission rate test of various plastic films, plastic composite films, paper-plastic composite films, geomembranes, co-extruded films, aluminized films, aluminum foils, aluminum foil composite films, waterproof breathable films, etc. |
|
Sheet |
Water vapor transmission rate test of various engineering plastics, rubber, building materials and other sheet materials. Such as PP sheet, PVC sheet, PVDC sheet, etc. | |
|
textile |
It is used to test the water vapor transmission rate of textiles, non-woven fabrics and other materials, such as waterproof and breathable fabrics, diaper non-woven fabrics, non-woven fabrics for hygiene products, etc. | |
|
paper, cardboard |
It is suitable for the water vapor transmission rate test of paper and cardboard, such as cigarette-packed aluminum foil, Tetra Pak sheet, etc. | |
| Extended application |
Inverted cup test |
The film, sheet, and protective material samples are clamped in a moisture-permeable cup, the upper surface of the sample is covered with distilled water, and the lower surface is in a certain humidity environment, so that a certain humidity difference is formed on both sides of the sample, and the distilled water passes the test. The sample enters the environment, and the water vapor transmission rate is obtained by measuring the change of the weight of the permeable cup with time (Note: the inverted cup method is required to purchase the permeable cup) |
|
artificial skin |
Artificial skin needs a certain amount of water permeability to ensure good breathing performance after implantation in humans or animals. This system can be used to test the moisture permeability of artificial skin. | |
|
cosmetic |
Testing of the moisturizing properties of cosmetics (such as facial masks, wound dressings) | |
|
Medical supplies and auxiliary materials |
Water vapor permeability test of medical supplies and excipients, such as water vapor permeability test of plaster patches, sterile wound protection films, cosmetic masks, scar patches | |
|
solar back sheet |
Water Vapor Transmission Rate Test of Solar Backsheet | |
|
LCD film |
Water vapor transmission rate test of LCD film (such as mobile phone, computer, TV screen) | |
|
paint film |
Water resistance test of various paint films | |
|
Biodegradable film |
Water resistance test of various biodegradable films, such as starch-based packaging films, etc. |
l lBased on the test principle of the cup method, it is a professional water vapor transmission rate test system for thin film samples, which can detect the water vapor transmission rate as low as 0.1g/m2·24h; the configured high-resolution The load cell, on the premise of ensuring high precision, provides excellent system sensitivity.
l lWide range, high precision, automatic temperature and humidity control, easy to achieve non-standard testing.
l lStandard purging wind speed ensures constant humidity difference inside and outside the permeable cup.
l l The system automatically resets before weighing to ensure the accuracy of each weighing.
l lThe system adopts cylinder lifting mechanical structure design and intermittent weighing measurement method, which effectively reduces the system error
l lThe temperature and humidity test socket that can be quickly accessed is convenient for users to perform quick calibration.
l lProvides two quick calibration methods of standard film and standard weight to ensure the accuracy and versatility of test data.
l lPrecise mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the detection efficiency.
l lThe three moisture permeable cups can be tested independently, the test process does not interfere with each other, and the test results are displayed independently.
l lThe large-size touch screen is friendly to human-machine functions, which is convenient for users to operate and learn quickly.
l l Supports multi-format storage of test data, which is convenient for data import and export.
l l Support convenient historical data query, comparison, analysis and printing and other functions.

Using the test principle of the moisture permeable cup weighing method, at a certain temperature, a specific humidity difference is formed on both sides of the sample, and the water vapor enters the dry side through the sample in the moisture permeable cup. The weight change with time was used to obtain parameters such as the water vapor transmission rate of the sample.
