TruDefender™ FT and TruDefender FTi Handheld Chemical Identification

Identification is a critical challenge in the evaluation and mitigation of potential chemical threats. With Thermo Scientific™ TruDefender™ FT and TruDefender FTi handheld analyzers, hazmat teams, law enforcement, military and other first responders can rapidly identify unknown chemicals, explosives, and other hazardous materials directly in the hazard zone, protecting themselves and increasing public safety. The TruDefender FTi adds to this core functionality by providing a direct link to incident command or reachback support through embedded mobile phone technology.
