　　The application scope of the mask particle filtration efficiency detector is:

　　The mask particle filtration efficiency detector is suitable for medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, mask and respirator production enterprises, etc.

　　The mask particulate matter filtration efficiency detector is a device used to detect the filtration performance, protective filtration efficiency, and filtration effect of protective masks. Currently, masks are mainly divided into air filtration masks and air supply masks; The working principle and function of a mask are that it is a type of hygiene product that is generally worn on the mouth and nose to filter the air entering the mouth and nose, in order to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper, etc. By comparing the working principle, it is clear that the protective filtration tester is a testing item used to test the protective filtration performance of masks.

　　The mask particle filtration efficiency tester is used to test the percentage of bacterial suspended particles filtered out by mask materials at a specified flow rate. The use of dual gas path simultaneous comparative sampling method improves the accuracy of sampling and is suitable for performance testing of bacterial filtration efficiency of medical surgical masks by metrological verification departments, research institutes, medical mask production enterprises, and other related departments. Mainly used for metrological verification departments, research institutes, medical mask production enterprises, etc.
