Superior Handheld Imagery And Accuracy

  • Optimal Ergonomics

    The T660’s optical block rotates 120° for easier targeting, while auto-orientation means the screen is always easy to read.

  • Efficiency and Productivity

    From the touchscreen to GPS/compass annotations and on-screen sketch, the T660’s features improve efficiency and boost productivity.

  • Fast Communication

    Connect (Wi-Fi) to FLIR Tools Mobile for image analysis and sharing, or transmit test & measurement data to the camera via METERLiNK®.
