FLIR now gives you a low-cost, easy-to-use option that doesn't sacrifice the reliable clarity and performance you need — the FLIR K33. This TIC features FSX™ Flexible Scene Enhancement, which intensifies structural and textural details in thermal images. The enhanced perspective and orientation helps improve situational awareness and give firefighters a greater sense of confidence and safety.

Firepower simplified

One glove-friendly button starts the K33 in TI-Basic mode, while one trigger-pull captures stills or records video.

Uncompromising visual quality

240 × 180 resolution, a 60 Hz frame rate, and a bright 4" LCD all help you see more in smokey conditions.

Affordability redefined

The K33's affordable price helps fire and rescue departments get essential tools into the hands of those who could use them most.
