FirstDefender™ RMX Handheld Chemical Identification

Responder and community safety are critical when analyzing potentially hazardous materials. Military and civilian first responders need to quickly identify unknown solid and liquid chemicals down range including explosives, toxic industrial chemicals, chemical weapons, narcotics, precursors, white powders and more. The Thermo Scientific™ FirstDefender™ RMX Handheld Chemical Identification Analyzer can be used as a handheld instrument or integrated onto a tactical robot, providing more flexibility and increased safety in incident response situations that call for rapid, accurate chemical identification.
