TG54/TG56
Spot IR Thermometers
The TG54 and TG56 Spot IR (Infrared) Thermometers provide non-
contact sur face temperature readings so you can quickly and easily take 
measurements in places that are out of reach. Providing a distance -to-spot 
ratio of up to 30:1, the TG54 and TG56 can measure smaller targets from 
a safer distance. New mode options give you control to view your current 
reading and last two temperature readings simultaneously. The TG54 and 
TG56 are built with a color screen that makes it easy to navigate and select 
settings, plus adds visibility and efficiency to the advanced feature set. The 
TG54 and TG56 are your go-to, pocket-sized devices for efficient temperature 
measurement.
