Determination of the water vapor transmission rate of materials. By measuring the water vapor transmission rate, the technical indicators of products such as non-adjustable packaging materials can be controlled.

II.Product Applications

Basic Application	Plastic film	Water vapor transmission rate testing of various plastic films, plastic composite films, paper-plastic composite films, co-extruded films, aluminum-coated films, aluminum foil composite films, glass fiber aluminum foil paper composite films and other film-like materials.
	Platic sheet	Water vapor transmission rate testing of sheet materials such as PP sheets, PVC sheets, PVDC sheets, metal foils, films, and silicon wafers.
	Paper,carboard	Water vapor transmission rate testing of composite sheet materials such as aluminum-coated paper for cigarette packs, paper-aluminum-plastic (Tetra Pak), as well as paper and cardboard.
	Artificial skin	Artificial skin needs a certain degree of water permeability to ensure good respiratory performance after being implanted in humans or animals. This system can be used to test the moisture permeability of artificial skin.
	Medical supplies and auxiliary materials	It is used for water vapor transmission tests of medical supplies and excipients, such as water vapor transmission rate tests of materials like plaster patches, sterile wound care films, beauty masks, and scar patches.
	Textiles, non-woven fabrics	Testing of water vapor transmission rate of textiles, non-woven fabrics and other materials, such as waterproof and breathable fabrics, non-woven fabric materials, non-woven fabrics for hygiene products, etc.
Extended application	Solar backsheet	Water vapor transmission rate testing applicable to solar backsheets.

	Paint film	It is applicable to the water resistance test of various paint films.
	Cosmetics	It is applicable to the test of the moisturizing performance of cosmetics.
	Biodegradable membrane	It is applicable to the water resistance test of various biodegradable films, such as starch-based packaging films, etc.

III.Product characteristics

1.Based on the cup method testing principle, it is a water vapor transmission rate (WVTR) testing system commonly used in film samples, capable of detecting water vapor transmission as low as 0.01g/m2·24h. The high-resolution load cell configured provides excellent system sensitivity while ensuring high precision.

2. Wide-range, high-precision, and automated temperature and humidity control makes it easy to achieve non-standard testing.

3. The standard purge wind speed ensures a constant humidity difference between the inside and outside of the moisture-permeable cup.

4. The system automatically resets to zero before weighing to ensure the accuracy of each weighing.

5. The system adopts a cylinder lifting mechanical junction design and intermittent weighing measurement method, effectively reducing system errors.

6. The temperature and humidity verification sockets that can be quickly connected facilitate users to perform rapid calibration.

7. Two rapid calibration methods, standard film and standard weights, are provided to ensure the accuracy and universality of the test data.

8. All three moisture-permeable cups can conduct independent tests. The test processes do not interfere with each other, and the test results are displayed independently.

9. Each of the three moisture-permeable cups can conduct independent tests. The test processes do not interfere with each other, and the test results are displayed independently.

10. The large-sized touch screen offers user-friendly human-machine functions, facilitating user operation and quick learning.

11. Support multi-format storage of test data for convenient data import and export;

12.Support multiple functions such as convenient historical data query, comparison, analysis and printing;

IV.Test the principle

The principle of the moisture permeable cup weighing test is adopted. At a certain temperature, a specific humidity difference is formed on both sides of the sample. Water vapor passes through the sample in the moisture permeable cup and enters the dry side, and then is measured

The change in the weight of the moisture permeation cup over time can be used to calculate parameters such as the water vapor transmission rate of the sample.

V. Meeting the standard:

Humidity control range	Weight loss method: 90%RH to 70%RHWeight gain method: 10%RH to 98%RH (The national standard requires 38℃ to 90%RH) The definition of humidity refers to the relative humidity on both sides of the membrane. That is, for the weight loss method, it is the humidity of the test cup at 100%RH- the humidity of the test chamber at 10%RH-30%RH. The weight gain method involves the humidity of the test chamber (10%RH to 98%RH) minus the humidity of the test cup (0%RH) When the temperature varies, the humidity range changes as follows: (For the following humidity levels, the customer must provide a dry air source; otherwise, it will affect the generation of humidity.)
