Based on the test principle of the cup method, it is a professional water vapor transmission rate (Drick) 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.
Wide range, high precision, automatic temperature and humidity control, easy to achieve non-standard testing.
Standard purging wind speed ensures constant humidity difference inside and outside the permeable cup.
The system automatically resets before weighing to ensure the accuracy of each weighing.
The system adopts cylinder lifting mechanical structure design and intermittent weighing measurement method, which effectively reduces the system error
The temperature and humidity test socket that can be quickly accessed is convenient for users to perform quick calibration.
Provides two quick calibration methods of standard film and standard weight to ensure the accuracy and versatility of test data.
Precise mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the detection efficiency.
The three moisture permeable cups can be tested independently, the test process does not interfere with each other, and the test results are displayed independently.
The large-size touch screen is friendly to human-machine functions, which is convenient for users to operate and learn quickly.
Supports multi-format storage of test data, which is convenient for data import and export.
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.
