Champion Engineering’s EZsmoke nontoxic smoke leak detector lets technicians test for leaks with a dense citrus-scented smoke easily seen when it escapes from any leak point. Its UltraTraceUV smoke solution with UV dye marks leaks in hard-to-reach, hard-to-see places by depositing at the site any leak smoke escapes from. It comes in a hard-shell wheeled carry-case, weighing 30 lb., with all needed accessories and enough smoke solution for hundreds of tests. Remote-control operation requires only one person for set-up and testing.
