Mask Leak Testing Device
Protective Mask Leakage Tester
The PortaCount Respirator Fit Tester is a portable device designed to detect the service performance and applicability of protective masks, and provide leaks and service performance testing for specified nuclear, biological and chemical defense (NBCD) / chemical, biological and radiation defense (CBR-D) masks and components without the need for the operator to wear a mask.
Overall Mask Leakage Test : Mask leakage is measured while the mask is challenged with an aerosol, with or without a plugged filter canister attached.
Leakage Isolation Test: Leaks normally invisible to the naked eye are easily isolated so that repair/replacement decisions can be made.
Mask Leak testing device Applications
Wind exhaust Valve Test: In the wind exhaust valve test, suspended particles as a function in the mask test and isolation detect the airflow leakage under strictly controlled conditions.
Drink Tube Flow Test: Tube blockage can be measured.
Drink Tube Valve Leakage Test: The drink tube valve is tested for leakage under controlled pressure.
