Mask Leakage Tester A leakage isolation test allows the operator to isolate the location of a leak and possibly remedy the situation; thereby permitting the continued fielding of the mask. Mask components that are prone to leaks include: voicemitters, exhalation ports and disks, inlet port seals, and drink hoses and couplings. The user interface is a simple, easy to use touchpad and digital display. A universal power supply ensures the unit is operable almost anywhere in the world. All tools and materials are neatly stored and transported in a rugged self-contained PelicanTM case.
