The perfect tool for arson investigators, Spectronics’ Maxima 3500M quickly detects accelerant (gasoline, kerosene, and other hydrocarbons) residues, which fluoresce visibly under the UV light. It is battery-operated, easily rechargeable, dent-proof, shock resistant, and has a stay-cool handgrip. The instant on/off/restrike reduces inspection time significantly by eliminating warm-up delay.
