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.
3.Technical parameters of the tester
1. Flowmeter range: 8L/min.
2. Control mode: computer.
3. The micromanometer has a measuring range of 0-500pa and an
accuracy of 1pa.
4. Timing accuracy: 0.1s.
