Building maintenance companies make use of our marking pens for permanent marking of equipment such as generators, furnaces, trash compacter systems, elevators, you name it. Our Mighty Marker® PM-16 is the favorite pen for this use due to its versatility and durability.
Hotels have made use of the UVSecurity® UV ink markers, which are only visible unless under ultra-violet light, in their cleaning inspection process. To check if an area has been cleaned properly, companies have turned to making invisible marks on toilets and other surfaces in need of meticulous attention for the sake of hygiene. If your mark is still visible under a UV lamp, the surface has been cleaned.
