Respirator Fit Tester
The Protective Mask Leak 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. PMLT can be set for timing by minutes, fully integrated in a rigid transportable box. Through a universal clamping assembly, inflated mask seals and fixture adapters, the PMLTcan virtually measure any type of gas masks in the world. Lightweight plastic heads are available in 2 sizes and are easily interchangeable with different sizes of masks. PMLT protective mask leak tester utilizes advanced transistor circuit and menu-driven touch pad to provide alphanumeric display.
Mask Leak testing deviceApplications
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.
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.
