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 pulling and holding the trigger freezes the image.
• 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.
