Infrared thermometer measurable temperature range

QHow far away can an infrared thermometer take readings?


In general, there is no limit on the measuring distance for infrared thermometers, but the field of view becomes problematic. Infrared thermometers work by detecting infrared energy emitted from the object being measured. The distance at which measurement is performed should be determined based on the infrared thermometer’s measuring field of view. While this differs depending on the model, the further away the instrument, the larger the field of view. Keep in mind that the temperature reading represents the average temperature in that field of view.
