Mask filtration efficiency tester

Protecting Employees: One Minute Mask Quick Test

PALASThe developed mask filtration efficiency tester is designed to quickly and efficiently test protective masks before use. The system can also be used for training purposes, as it can immediately display the efficiency of the protective mask.

Function:Place the mask on the test head before use. By using a high-resolution aerosol spectrometer, particulate pollutants (size and pollutants) in the air can be measured. After the device automatically switches and determines the particle contamination after mask filtration. This can be automatically repeated multiple times. The ratio between two measurement values is used to determine the protection level of the mask. Quickly determine if the mask is usable.

Protection level:The level of protection provided by a mask depends on the filtering effect of the mask material and the correct wearing on the head. Leakage may occur (due to air passing through the material or entering from the unfiltered part of the mask), affecting the protective effect. At the same time, the standard head test of the mask rapid inspection device imitates the filtration of external particles by real masks.

The measurement of indoor particulate pollutants and the measurement of respiratory airflow behind masks both use high-resolution aerosol spectrometers, which can accurately measure particle size170Nano to5A virus between micrometers. Therefore, it can also be used to determine the level of protection against viruses. For example, aerosols during coughing can be as high as5μmOr larger, at this time, complete detection can be carried out through the measuring device.
