  • Flir T640 Thermal Camera for Predictive Maintenance w/15° Lens, Wi-Fi

The high-performance FLIR T640 helps you find hidden signs of electrical resistance, mechanical wear, and other heat-related problems. 

Offering the rich detail of MSX®, the enhanced resolution FLIR UltraMax®, and temperature calibration to 2000°C, the 307,200 (640 x 480) pixel T640 has the superior image quality and clarity needed to diagnose problems quickly, so you start on repairs immediately.

Keep things operating safely and head off expensive downtime with this flexible, dependable thermal imaging camera.


  • The T640's optical block rotates 120° for easier targeting, while auto-orientation means the screen is always easy to read.
  • From the touchscreen to GPS/compass annotations and on-screen sketch, the T640's features improve efficiency and boost productivity.
  • Connect (Wi-Fi) to FLIR Tools Mobile for image analysis and sharing, or transmit test & measurement data to the camera via METERLiNK®.
