True Defender FT is a FTIR Hand-Held Spectroscopy Device by Thermo Scientific.

TruDefender FT and TruDefender FTi

Thermo Scientific TruDefender FT is a handheld FTIR system designed to analyze and identify unknown chemical substances directly in the hazard zone. The TruDefender® FTi adds to this core functionality by providing a direct link to incident command or reachback support through embedded mobile phone technology. Using industry-proven FTIR technology, TruDefender FT and TruDefender FTi complement the FirstDefender product line to maximize in-the-field coverage of an even broader range of unknown chemicals.

Software Update: TruDefender FT/FTi v1.5.
