Leak detectors and anoxia

Has anybody used an ultrasonic leak detector to check the integrity
of Marvel-seal enclosures used in anoxic fumigations.  I'd be
interested to hear if they work for this application.  Using an
ultrasonic leak detector vs. a combustible gas detector would seem
to eliminate the need to use "Dust-off" or similar products as a
tracer.
