GA-TQL50-1 Tester nizke prepustnosti
Uvod
The GA-TQL50-1 Low Permeability tester uses new technology and the most common test methods to measure the permeability of thin films, papers, and other flake objects. This instrument is a special instrument for testing ultra-low wafer permeability. Je popolnoma avtomatiziran instrument, ki ga nadzira mikroračunalnik z enim čipom. Its test methods meet the requirements of Schober and Bentsen and Gerlai and other methods, and it is an advanced instrument for testing air permeability in the plastic film, paper making, packaging, medical and automotive industries, and its performance meets international standards.
Načelo
According to the principle of pressure difference method, the pre-treated sample is placed between the upper and lower measurement surfaces, and a constant pressure difference is formed on both sides of the sample. Under the action of pressure difference, the gas flows from the high pressure side through the sample to the low pressure side, and the permeability of the sample is calculated according to the area, pressure difference and flow rate flowing through the sample.
