The PosiTest3 from Draeger Safety, Inc. determines the proper operation of SCBAs by using dynamic tests and functional checks that quantitatively determine whether or not the SCBAs meet NIOSH and NFPA requirements. Consuming less than 1 percent of the air supply, PosiTest3 evaluates any fully assembled SCBA in less than two minutes. Completed tests can be stored and printed.Draeger Safety, Inc., Pittsburgh, PA.
