WVTR-C6 Water Vapor Transmission Rate Tester is designed and manufactured based on the gravimetric method and can be used to test the water vapor transmission rate of plastic films, composite films, sheets, and other materials used in the packaging, medical, and construction industries.

Features

● Based on the gravimetric method, testing of thin film sample water vapor transmission rate (WVTR) as low as 0.1g/m2•24h

● High resolution weighing sensor provides excellent system sensitivity, ensuring high accuracy.

● Wide range, high precision, automatic temperature and humidity control, easy to achieve non-standard testing

● Standard purging speed ensures constant humidity difference between inside and outside the cup

● Zero clearing before weighing to ensure the accuracy of each weighing

● Cylinder lifting mechanical structure design and intermittent weighing measurement method effectively reduces the system error

● Rapid access to temperature and humidity verification socket for users to carry out rapid calibration.

● The precise mechanical design ensures the ultra-high precision as well as high detection efficiency

● 6 permeable cups can be independently tested, the test process does not interfere with each other, and the test results are independent display.

● Large size touch screen friendly man-machine function, convenient for user operation and quick learning.

● Support test data multi-format storage, convenient data import and export.

● Support convenient historical data query, comparison, analysis and printing and other functions.

Technical Specification parameters

Test Principle

Using the moisture permeable cup weighing test principle, at a certain temperature, the two sides of the sample formed a specific humidity difference, the water vapor through the moisture permeable cup into the dry side of the sample, by measuring the weight of the moisture permeable cup changes with time, the water vapor permeability of the sample and other parameters.
