Using an infrared thermometer is the safest way to measure surface temperatures of hot, hard to reach, electrically
energized or moving objects. It is commonly used to verify HVAC distribution, check for overheated wires, radiant heat
in oors, running motors, insulation, pipes, breakers, and corroded connections. They are also excellent tools for
reading ceiling duct temperatures from the oor without a ladder!

The large style infrared thermometers include extra features such as a built-in LED ashlight (used in environments with
minimal lighting e.g., boiler rooms) and Hi / Lo Alarms for quick indication when temperatures exceed a set range. The
magnetic stand allows the instrument to be quickly mounted to metal surfaces making it hands free

D:S (Distance to Spot Ratio)
The further away from the object, the larger the surface area measured.
Optical resolution is expressed as a ratio of the distance to the resolution spot
divided by the diameter of the spot.
