Portable Sniffing Applications
Some applications require operators or technicians to look for leaks from a ladder, outdoors,
above or below ground, or in a densely constructed industrial facility or power plant. In
these cases, a mobile cart-mounted MSLD may not be practical. A truly portable unit such
as the PHD-4 is required. Some examples of such applications are:
❑ Aircraft manufacturing and maintenance
❑ Power generating plants
❑ Pressurized pipelines
❑ Bioreactors and fermenters
❑ Petrochemical plants and refineries
❑ Underground tanks
Large condensers or heat exchangers
