Provide a variety of mask testers with high precision and easy to use. It is used to test medical masks, disposal masks, KN / KP 90 / 95 / 100, N / P / R 95 / 99 / 100, FFP 1 / 2 / 3, KF 80 / 94 / 99 dust masks etc. The test indexes include filter efficiency (penetration efficiency), resistance, exhalation resistance, inhalation resistance, leakage air flow of the exhalation valve, difference pressure of medical face mask, mask defects, etc.
It is used for the performance test of Class F filters. It can test the resistance, ePM1.0, ePM2.5, ePM10.0, and the flow resistance curve of various types of filters, including flat, W-type, bag and cylindrical filters.
The SC-RT-N1704 Respirator Valve Air Tightness Tester is used to test the leakage air flow of the exhalation valve of the mask.
