The FLIR TG275 is an Automotive Diagnostic Thermal Camera that combines non-contact temperature measurement with thermal imaging in a single handheld troubleshooting tool. It is designed to help technicians quickly locate the source of heat-related problems and identify potential faults encountered during automotive maintenance and repair work.

According to FLIR, the TG275 is intended for automotive maintenance and repair diagnostics, where finding the source of heat-related problems and spotting potential faults are the primary tasks. The instrument pairs a 160 x 120 pixel thermal imager with a visible spectrum camera so technicians can correlate thermal patterns with the physical detail of the area under inspection.

## Brand Heritage

FLIR Systems, headquartered in Wilsonville, Oregon, was acquired by Teledyne Technologies in 2021 and now operates as part of the Teledyne FLIR business. The FLIR brand and product lines, including the TG-series test and measurement thermal cameras, have been maintained under the new ownership.
