mask q-check

the mask q-check was developed by palas to subject protective masks to a quick, simple and yet meaningful test before use.
the system can also be used for training purposes as it immediately shows the efficiency of protective masks. functionality:
the mask is placed on the test head before use. using a high-resolution aerosol spectrometer, the particle contamination (size
and contamination) in the ambient air is measured. afterwards the device switches automatically and determines the value
of the particle contamination behind the protective mask. this can be repeated automatically several times. the ratio of the
two measured values is used to determine the degree of protection of the protective mask. a simple display immediately
shows whether the mask can be used. degree of protection: the degree of protection provided by a respirator depends on
the filtration effect of the mask material as well as the correct fit on the head. leakage can occur (i.e. air passes the material
and enters behind the mask unfiltered), which can affect the protective effect.means of the test on the standard head with
the mask q-check, both effects are simulated simultaneously and the real protective effect of the mask against particles in the
outside air is measured. quality of the measurement: the mask q-check works in suction mode with a volume flow of 95
l/min, defined according to en149 or en143, which corresponds to the maximum human breath. the measurement of particle
contamination in the room and after the breathing mask is carried out by means of a high-resolution aerosol spectrometer,
which precisely measures particle sizes from 170 nm to 5 μm. thus, the protective effect of viruses is also determined. the size
of droplets when coughing, for example, can be up to 5 μm or larger and is therefore fully detected by this measuring device
during the test.
the mask q-check, safe on-site testing of respiratory masks is therefore possible automatically within 1 to 5 minutes.
