How do the different Flir K series color modes present temperatures?

NFPA fire fighting mode

For initial fire attack and life rescuing operations.

  • Yellow starts at 150°C (302°F)
  • Orange starts at 300°C (572°F)
  • Red starts at 450°C (842°F)
  • Dark red (saturated value) > 650°C (1202°F)

 

Black and white fire fighting mode

Same as the NFPA colorized fire fighting mode but a grey scale image.

 

Fire mode

For use in context with higher background temperatures. For example structural fires. Where there is already a lot of open flames and a high background temperature.

  • Yellow starts at 250°C (482°F)
  • Orange starts at 400°C (752°F)
  • Red starts at 500°C (932°F)
  • Dark red (saturated value) > 650°C (1202°F)

 

Search and rescue mode

For use in context with lower temperature. For example initial search and rescue operations. Search for people in landscapes, traffic accidents etc.

  • Yellow starts at 100°C (212°F)
  • Orange starts at 125°C (257°F)
  • Dark red (saturated value) > 150°C (302°F)

 

Heat detection mode

The heat detection mode is optimized for searching hotspots during overhaul after the fire is out—typically to ensure that there is no hidden fire left. This mode can also be used to find thermal patterns, for example signs of people in car seats after accidents, to ensure that everyone has been found. This mode can also be used to search for people in water and open landscapes.

  • High-sensitivity range only.
  • Colorization of heat: the 20% highest temperatures in the scene.
  • High-sensitivity range: –20 to +150°C (–4 to +302°F).
