Product name£ºFace Mask Air Flow Resistance and Differential Pressure Tester

Product model£ºRH-TQK490

Download£ºFace Mask Air Flow Resistance and Differential Pressure Testerdownload

 Working Principle:


Air permeability test of mask:
Input 8L / min air flow to the tested sample under the test area of 4.9cm². Measure the pressure difference between the two sides of the tested sample


Air permeability test of textiles:

According to the principle of pressure difference method, place the pre-processed sample between the upper and lower test heads. A constant pressure difference is formed on both sides of the sample. Under the action of pressure difference, the air flows from the upper test head through the sample to the lower test head, and the air permeability of the sample is calculated according to the area, pressure difference and flow rate of the sample.\\
