Mask pressure difference tester
Scope of application:
It can be used to measure the gas exchange pressure difference of
medical surgical masks and other textile materials. It is used to
measure ventilation resistance and pressure difference of mask
under specified conditions. It is applicable to the inspection of
medical respirators under the conditions of inspection and
inspection of medical respirators.
It is applicable to the relevant testing and inspection of medical
surgical masks and disposable medical masks conducted by * labor
protection articles inspection institutions and mask manufacturers.
