FLIR TG56 Spot IR (Infrared) Thermometer FLIRs TG56 Spot infrared thermometers provide non-contact surface temperature readings. Operators can quickly and easily take measurements in hard to reach places. Providing a distance-to-spot ratio of up to 30:1, the TG56 can measure smaller targets from a safer distance. Mode options enable you to view the current reading and last two temperature readings simultaneously. TG56 is built with a Color screen that makes it easy to navigate the devices and select settings. FLIR IR thermometers have a rugged, industrial design that can withstand a 3 m drop. A bright LED work light helps make a target visible in poor lighting conditions. The slim, light design is convenient to carry in your back pocket wherever you go. TG56 features a general purpose Type K input thermocouple.
