Audited Supplier LR-EN149 Breathing Resistance Tester testing machine Mask respiratory resistance tester
Use
Respiratory resistance tester is suitable for measuring the inspiratory resistance and expiratory resistance of respirators and respirator protective equipment under the standard, and it is also used for testing and testing of common mouth mask products by manufacturers of national labor protection equipment inspection institutions.The instrument USES the latest technology, no external air source is needed for automatic test, and no additional manual adjustment instrument is needed during test. After taking the test sample, press the test button 10~20s to simultaneously detect the inspiratory resistance and expiratory resistance and display the test results.The internal sensor of the instrument is the high-precision digital sensor of SMI company (precision 1%), which guarantees the accuracy of the test results.The instrument is equipped with a thermal printer to print test results.

Detection method:
Check the air tightness and working condition of the testing device.Set the inhalation speed and exhalation speed to the required standard speed.According to GB/T 32610-2016, the expiratory speed and inspiratory speed should be set to 85L/min.The expiratory speed was set to 160L/min and the inspiratory speed was set to 30L/min and 95Lmin according to standard BSEN149.
Take appropriate measures (such as use of sealants) and wear the tested sample in an airtight manner on the matching test head mold. Ensure that the mask is worn in the correct position and that the fixing method does not affect the effective ventilation area of the filter element or deform the mask.Press the test button and the instrument will automatically start the test and measure the inspiratory resistance and expiratory resistance at the same time. The test will take about 10~20s.
