EN149:2001+A1-2009
Respirator respiratory resistance tester is used to test the
respiratory resistance of self-priming filter type particulate
respirator. The equipment is equipped with software, which can
display pressure curve in real time, output test report and save
test data.
2, Equipment features
1. The equipment is equipped with vacuum pump and air pump, which
is used to simulate artificial respiration.
2. The pressure sensor and pressure sensor are used to collect data
and test data.
3. The pressure has the function of stepless adjustment, and the
technical parameters such as the holding pressure and holding time
can be set.
4. High precision programmable touch screen.
5. The European standard en149 respirator resistance tester adopts
high-precision imported digital flowmeter with high flow control
accuracy.
6. The respirator can be set in two modes to detect the breathing
resistance.
7. The automatic switching device of respirator pipeline solves the
problem of pulling out the pipe and connecting the pipeline by
mistake when testing.
