Providing 640x480 resolution and radiometric video recording

The pinnacle of the thermal imaging camera market, the FLIR T660 Thermal Imager offers the best performance and latest technology available. Offering the user excellent camera ergonomics and an easy-to-use interface, the T660 captures superior thermal images with a 640x480 thermal resolution (the highest resolution currently available on the commercial market), as well as providing incredibly accurate temperature data with an accuracy of +/- 1% or 1°C (within a limited temperature range).

The FLIR T660 benefits from FLIR's innovative MSX® Technology, underlaying the digital image underneath the thermal image to produce more visual detail and definition on the image. The T660 also supports UltraMax™, enabling a substantial enhancement of thermal images after exporting into FLIR Tools software with four times as many pixels and 50% less noise.

The FLIR T660 has a very wide temperature range dectetion thermal radiation down to -40°C and up to 2000°C and is thermally sensitive down to 20mk (0.02°C).

The T660 is also the perfect choice for thermal video recording, with a unique feature allowing Radiometric video recording (CSQ) to memory card. This allows temperature data to be added post-transfer onto video files using FLIR Tools Plus software. Normally video recording tends to be non-radiometric.

Quick overview of FLIR T660 Thermal Imaging Camera:

  Thermal Resolution
640x480 pixels (307,200 temperature measurements - x4 using Ultramax™).
  Thermal Sensitivity
<0.02°C @ 30°C
+/- 1% or 1°C whichever is greater - Truly market defining!
  Temperature Range
-40°C to 2000°C
Up scales your thermal image within FLIR software by x4 increasing definition and reducing noise. Allows zoom on smaller targets for more accurate measurements.
Patented multi-spectral dynamic imaging provides digital image detail from the visible light camera onto the thermal image. This makes it so much easier to identify the image visually and thus improving work efficiency.
  Radiometric Video Recording
Video containing temperature data can be exported to memory card for further analysis within FLIR Tools PLUS software.
  Auto Orientation
Automatically orients onscreen data to portrait or landscape view.
  Rotatable Lens
Scan targets overhead, under objects, and from tough angles effortlessly with the help of a lens system that lets you point 120° up or down while keeping the display in easy view.
  User Presets
Pre-programmed user pre-sets makes it quicker and easier to obtain the measurements required.
  Intuitive Touch screen and Interface
Tap the 4.3" Touch screen or use buttons to quickly access temperature and measurement tools, parameters, image modes etc.
