A translucent yellow spray that turns purple immediately upon contact with even small drops of acid of pH 2.6 or lower has been added to the Allison Engineering range of OnGuard acid detection products.
After a confirmed or suspected acid spill has occurred, Acid Spot’R will define the perimeter and extent of the leak or spill. Once it has been cleaned up, the affected area can be retested.
The spray works well on most surfaces, and has applications in laboratories, at weld sites, on valves, pipes, flanges or pumps, on tools, in or around containment areas, and in loading/unloading zones. It is effective on hydrofluoric, hydrochloric, sulphuric, nitric, trifluoroacetic, citric, phosphoric, glacial acetic and other acids with a pH of 2.6 or below.
