FLIR T-Series Infrared Camera Features

Introducing the New FLIR T1K

We've been working towards this for 50 years: the thermal camera you've always wanted. Born out of five decades of infrared expertise and a keen understanding of the expert's needs, FLIR's new T1K offers outstanding infrared performance, with no sacrifice or compromise. FLIR's flagship T1K redefines the limits of infrared imaging: true HD resolution, precision lenses like no others on the market, more than twice the thermal sensitivity of legacy uncooled systems, and the ergonomics and responsive user interface needed to make your workday easier. Find hidden hot spots faster, measure more accurately, and be the hero with FLIR's infrared powerhouse, the T1K.

It's all About the Details

The T1K is designed to be compact, streamlined, and easy to use. FLIR's engineers focused on advancing the thermal and optics technology without adding bulk to the overall T-Series design. The result is a thermal camera that works with you. The viewfinder plus the 120° rotating optical block allow you to point the T1K in multiple directions while maintaining a comfortable position. The glare-reducing eyecup on the high resolution viewfinder improves scanning in daylight conditions. And, the joystick and programmable buttons let you control the camera with a finger or thumb – no need to change your grip.
