The FLIR TG165 Imaging IR Thermometer combines elements of a thermal camera and an infrared thermometer to make precise temperature measurements. More than just good measurements, the imaging function of the TG165 ensures that the measurement is taken at the right location. While normal spot guns may leave you guessing as to the best place to measure, the FLIR Imaging Thermometer will let you immediately see the hot and cold areas, so you can make a more informed decision. Better information during your diagnostics will lead to better solutions, more satisfied customers, and the peace of mind that you got it right.


The face of the FLIR TG165 features both a thermal camera and an infrared thermometer. The thermal camera uses the FLIR Lepton core with a resolution of 80 x 60, for a total of 4800 pixels. At the close distances where you would normally use an infrared thermometer, the TG165 has enough resolution to help you understand what you are seeing, and to pinpoint any high or low temperature areas. The TG165 thermal camera can view objects and scenes up to 260 °F (127 °C), and is sensitive to temperature variations as small as 0.15 °C, giving a good picture of temperature gradients across a target. With the wide angle lens of the TG165, the thermal camera shows a large area, even when standing very close to a target.

Temperature Measurement

While the thermal camera of the FLIR TG165 helps you quickly identify areas, the infrared thermometer provides the accurate temperature measurements to make critical decisions. The thermometer can precisely measure temperatures from -13 to 716 °F (-25 to 380 °C), to cover a wide range of encountered problems. Twin lasers help locate the exact target measurement area at any distance, while a convenient on-screen crosshair marks the spot as well. The distance to spot ratio of the FLIR TG165 is a very good 24:1, more than twice that of most other infrared temp guns.


FLIR has designed the TG165 to be quick and especially easy to use. Press and hold the power button for 3 seconds to power up the unit. Startup time is a minuscule 2 seconds until the TG165 is ready to measure. The screen shows a live thermal view of the area and the temperature of objects in the crosshairs. When an anomaly is discovered and you need to capture an image, simply pull the trigger. While holding the trigger down, twin lasers appear to mark the measurement area. The screen shows the temperature of the area between between the lasers. An image is captured automatically when the trigger is released, and you have the option to save or delete the image. Saved images are stored to the on board micro SD card, an can be recalled on screen or downloaded.

Image Download

Images stored to the micro SD card on the FLIR TG165 can be downloaded to any computer using the included USB cable. Or if you prefer, just remove the SD card and use a card reader connected to your computer. Saved images are stored in bmp format, and do not include radiometric data. The bmp images can be imported into almost all software for easy organization and reporting. The TG165 uses an internal, rechargeable lithium ion battery that is charged through the micro USB port on top of the device. One charge of the battery is good for a full 8 hours of typical operation. The FLIR TG165 Imaging IR Thermometer is housed in tough rubberized plastic, and is rated to withstand a six foot fall. It is a rugged yet precise imaging thermometer that professionals can count on for accurate diagnostics on a daily basis.
