Mask resistance tester
1.Test standard: yy0469-2011 medical surgical mask
Differential pressure tester is used for pressure difference detection of surgical masks. The equipment is equipped with software, which can display pressure curve in real time, output test report and save test data. Meet the test standard yy0469-2011 surgical mask 5.7. YY/ t0969-2010, ventilation resistance 5.6
2. Features of equipment
1. The equipment is equipped with an air pump to simulate artificial respiration.
2. The detector is equipped with positive pressure sensor, which is used to collect the pressure of test data and reflect it to the computer software.
3. The pressure has a non-polar adjustable function, and the technical parameters such as the pressure holding time can be set.
