GBN701 Face Mask Air Flow Resistance and Differential Pressure Tester

Application：:

Used for face mask air flow resistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger.

Standards

YY0469-2011, YY0969-2013

Principle

The output of the air flow is set by a gas flow meter, the air flow passes through a certain area of the test sample, the current pressure is detected by a pressure sensor, and the pressure difference is calculated.

Features

  • Equipped with special sample grip, easy to use.
  • Built-in HD touch screen.
  • Built-in micro printer, easy to print test results.
  • Equipped with high-precision differential pressure sensor, digitally display the pressure difference between the two sides of the sample;
  • Test time can be adjusted according to test requirements
