High Efficiency of Respiratory Resistance Testeris used to measure the respiratory resistance and expiratory resistance of respirators and masks under the specified conditions. Applicable to the national labor protection supplies inspection agency, mask manufacturers related inspection and inspection of ordinary masks, dust masks, medical masks, anti-fog mask products.

High Efficiency of Respiratory Resistance Testercan be used to determine the inspiratory and expiratory resistance of masks under specified conditions.Another additional function of this machine is flow impact test of the breather valve. The flow rate for inhale resistance test is 30L/min and 95L/min. The flow rate for exhale resistance test is 160L/min. And the flow rate for the flow impact test is 300L/min.

EN149-2009 section 7.15, 8.3.4, EN 13274-3, GB 19083, GB 2626, NIOSH 42 CFR Part 84, JIS/T 8151

1. Touch screen control, English menu, man-machine dialogue mode, easy operation.

2. Built-in thermal printer, it is convenient to quickly print test results on site.

3. Two modes of breath detection and inhalation detection can be set.

4. The automatic switching device of the respirator pipeline solves the problem that the tester pulls out the

pipe and accidentally connects the pipeline when testing.

5. 3D printed standard head mold, which simulates the actual inhalation and exhalation of the human body,

improving the accuracy of the data.
