FLIR TG165 Spot Thermal Camera


The FLIR TG165 Spot Thermal Cameras bridge the gap between single spot infrared thermometers and FLIR's legendary thermal cameras. Equipped with FLIR's exclusive Lepton® micro thermal sensor, these cameras let you see the heat so you know exactly where to target the measurement spot. Easily find unseen hot and cold spots for instant troubleshooting, and store images and data to show customers and include in reports.


Equipped with FLIR’s exclusive Lepton® micro thermal camera, the TG165 helps you identify heat patterns, reliably measure temperature, and store images and data for reports. And with a spot ratio of 24 to 1, you can take accurate readings from safer distances. The TG165 is simple to operate, featuring intuitive menu icons and dual laser pointers. Built by the world leader in thermal technology, the durable TG165 will quickly become your “go to” temperature tool.
