The Tracex Explosives Kit was developed by Morphix Technologies under contract from the U.S. Department of Defense and meets their demanding requirements. It is small enough to fit in a cargo pocket, lightweight, and rugged. Each kit comes in its own disposable protective plastic case. With a single swab, the Tracex Explosives Kit detects all the major families of explosive materials and their precursors. Due in part to Tracex's simple color-change alert system, a single color indicates the presence of a particular family of explosive material. The Tracex Explosives Kit can detect nine explosive families in under three minutes.
