The Mask Particulate Filtration Efficiency Tester is used for testing the filtration efficiency of daily protective masks, medical masks and melt-blown materials on particulate matter, as well as measuring the obstruction performance of common fabrics and medical protective masks on airflow with constant flow rate.
It is suitable for medical device inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, prevention and control center, textile testing center, hospital, mask manufacturing enterprises, etc.
Testing Principle
Its design and manufacturing according to the standards of YY 0469-2004and GB 2626-2006 , at the same time,  it also refers to the international advanced design concept of similar equipment (such as the United States TSI company), based on the European standard En 1822-3:1998 single filter material test principle, but it is also suitable for the test status of domestic relevant industry.
