FLIR K33 Thermal Imaging Camera

The FLIR K33 delivers clear, dependable thermal imaging in a rugged and easy-to-operate package built for fire and rescue applications. Its 240 × 180 thermal resolution, fast 60 Hz frame rate, and FLIR FSX® image enhancement help firefighters recognize structural details, locate hazards, and maintain situational awareness in smoke-filled environments.

Simplified Fireground Operation

The K33 is designed for straightforward operation while wearing structural firefighting gloves. A single glove-friendly button powers the camera on in TI Basic mode, while pulling and holding the trigger freezes the image for closer evaluation.

Enhanced Thermal Detail

FLIR FSX® Flexible Scene Enhancement strengthens edges, textures, and structural details within the thermal image. This enhanced perspective helps firefighters better identify walls, doors, objects, pathways, and other critical features in low-visibility conditions.

Clear, Responsive Imaging

A bright 4-inch LCD, 240 × 180 thermal resolution, and smooth 60 Hz image frequency provide clear, responsive thermal imaging during search, fire attack, overhaul, and scene assessment.

Built for Fireground Conditions

The K33 is IP67-rated, survives a 6.6-foot drop onto concrete, and withstands temperatures up to 500°F for five minutes. Its rugged construction is designed to perform in wet, dirty, smoky, and high-heat environments.
