☆Based on the cup method test principle, is a professional for thin film sample water vapor transmittance (WVTR) test system, can detect as low as 0.1g/m2•24h water vapor permeability; The high resolution weighing sensor provides excellent system sensitivity on the premise of ensuring high accuracy.
☆Wide range, high precision, automatic temperature and humidity control, easy to achieve non-standard testing.
☆Standard purge wind speed ensures constant humidity difference between inside and outside the cup.
☆The system automatically clears the zero before weighing to ensure the accuracy of each weighing.
☆The system adopts the cylinder lifting mechanical structure design and intermittent weighing measurement method, which effectively reduces the system error.
☆Rapid access to temperature and humidity verification socket for users to carry out rapid calibration.
☆Provide standard membrane and standard weight two fast calibration methods to ensure the accuracy and versatility of the test data.
☆The precise mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the 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.
