Q. How should we get the best result with digital infrared thermometer?

Answer

Keeping in mind the distance-to-spot ratio of the digital infrared thermometers, you can get close enough to the target so that the thermometer reads only the area that has to be measured. However, you need to keep a watch for shiny, low emissivity objects. Even steam or dust can affect the accuracy of digital infrared thermometers so that keep the lens of your thermometer clean and free of scratches.
