Our carousel scent wheel is made completely from stainless steel and fully welded to avoid scent traps and crevice corrosion.
Our competitors are made from Aluminum including the scent pots and lids. These scent pots are held horizontally and not vertically like our own. This creates a problem because the centrifugal force will push the contents toward the perforated lid during rotation making detection far easier!
Certain substances will also corrode the Aluminum fairly rapidly and any products held together with nuts and bolts create scent traps and promotes crevice corrosion.
