Introduction: Suitable for plastic film, composite film, fabric, leather, solar cells and other materials, as well as food, health, medical, textile and leather and other fields of determination of the permeability of a variety of materials. Determination of water vapor transmission rate, control the quality of materials for product quality inspection and control to provide accurate technical parameters. Measurable film, bottles and bags. Working principle: weighing method, in line with national standards. Control the test environment temperature, humidity, wind speed, the sample formed on both sides of the fixed humidity difference, water vapor through the sample into the dry side. Use the cylinder mechanism to enhance the moisture permeable cups and weigh the permeable cups at equal intervals. The mass loss of the permeate cup over time was measured and the moisture permeability and moisture permeability coefficient and other parameters of the sample were analyzed. Features: 1 fully automatic test: only need to set the temperature, humidity, preheating and stop conditions, start automatically after the test to determine the end of the test and save the test results; 2 power save function; full monitoring, automatic recording; sampling rate adjustable; 3 full monitoring, real-time recording, the entire reproduction of the test process; powerful graphical curve function, easy to compare and test, analysis; 4 host software has a common database system, the data can be derived for data storage, query, print, and other functions. Through the analysis of historical data, easy to grasp the history of the product.
