FLIR K33 Firefighting Thermal Camera - 60Hz, 240 x 180 Pixels

FLIR K33 Firefighting Thermal Camera

With simple, one-button operation, one-button image capturing and excellent thermal imaging quality, the FLIR K33 is a must-have for all professional firefighters.

New 2024 Improvements

FLIR has updated the Kxx-Series Thermal Cameras to improve the precision and speed of critical decision-making. First responders will benefit from:

  • Improved image clarity and sharpness
  • Greater contrast in low and high-contrast areas
  • More astute room and depth perception
  • Better image performance

These enhanced features work together to provide more efficient navigation and orientation in low and non-visibility areas and prevent user disorientation As a result firefighters can deliver more efficient and safe search and rescue operations, as well as faster fire location.

Serious Fire Protection

With the FLIR K33, firefighters can take their abilities to the next level. By using the power of thermal cameras, you'll be able to:

  • See through the dark and smoke
  • Spot the body heat of trapped individuals
  • Identify structural weakpoints and plan a course of action
  • Instantly capture thermal images with the press of a button

FLIR's K33 has the added benefit of an extremely high 60Hz frame rate, giving you smooth, clear images even when you're moving. Most thermal cameras offer frame rates of 9-15Hz - the bump up to 60Hz is an essential for firefighters who must react quickly to a wide variety of difficult challenges.

A clear, high quality 240 x 180 pixel thermal detector is also built into the K33, ensuring you get high quality thermal images either in real time or when capturing by squeezing the trigger.

Intense Detail with FLIR Flexible Scene Enhancement (FSX)

While traditionally thermal cameras display images as a series of blurs where you can only identify colours, FLIR's K33 doesn't.

Thanks to FLIR's unique FSX technology, the K33 will actively blend together digital and thermal images, enhancing detail significantly. Where before you only got a series of blurs, instead you'll be able to more accurately track your movement, identify clear structural problems and work safer, smarter and capture better quality images.

With the bright 4" LCD screen, the exceptional 60Hz frame rate and FLIR FSX all included as standard, FLIR's K33 includes all of the tools a firefighter needs.
