Aseptic Wound Protection Films and Medical Plasters

Feature:

Based on the cup method test principle, it is a professional water vapor transmission rate (WVTR) test system for thin film samples, which can detect water vapor transmission rates as low as 0.1g/m2·24h; equipped with a high-resolution scale The heavy sensor provides excellent system sensitivity while ensuring high accuracy.

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

The standard blowing wind speed ensures a constant humidity difference between the inside and outside of the breathable cup

The system is automatically cleared 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 quick-access temperature and humidity calibration socket is convenient for users to perform quick calibration

Provide two fast calibration methods, standard film and standard weight, to ensure the accuracy and versatility of test data

The sophisticated mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the inspection efficiency

The 6 breathable cups can be independently tested, the test process does not interfere with each other, and the test results are displayed independently

Windows-based operation interface, convenient for user operation and fast learning

Support multi-format storage of test data, convenient for data import and export

Supports convenient historical data query, comparison, analysis and printing and other functions
