Testing principles and characteristics of air permeability tester

Air permeability testerTest principle

Under a certain temperature and humidity, maintain a certain gas pressure difference on both sides of the sample and measure the low pressure of the sample The changes in lateral pressure of the gas are used to calculate the air permeability and the air permeability coefficient. Brief introduction to the testing process of BTY-B1P air permeability tester. After the test starts, the system automatically displays the relationship between air permeability pressure and time on the computer screen in real time. When the system default or stop condition is reached, the test stops and then, depending on the operator\'s needs, determines whether to issue a test report or perform other operations on the data.

Air Permeability TesterFeatures:
