Mask particle protection effect tester

Mask particle protection effect detector main use.


　　Mask particle protection effect detector is placed in the volume of 500L self-cleaning detection chamber national standard head model, the mask to be tested is worn on the head model, through the occurrence of median diameter of 0.6μm, the occurrence of concentration of 25mg/m3 of salt aerosol and median diameter of 0.3μm, the occurrence of concentration of 25mg/m3 of oil aerosol into the self-cleaning detection chamber, the head model to do sine curve simulation of breathing. Using upstream and downstream photometer sampling to detect the concentration of salt aerosol and oil aerosol before and after the mask, and calculate the filtering efficiency of the mask particulate matter. The mask to be tested can be worn on the national standard head model to automatically detect the breathing resistance.


 

Mask particulate matter protection effect detector application scope.

　　Applicable to medical device inspection institute, disease prevention and control center, hospitals, high efficiency filter manufacturers, mask research and development and manufacturers, etc. for the detection of mask, filter media and other particulate matter filtration efficiency.


Mask particulate matter protection effect detector applicable standards.

　　GB 32610-2016 daily protective masks technical specifications
