Infrared thermometers are popular non-contact temperature gauging instruments that are very much in vogue these days. And there are many factors that affect their reading accuracy. 
• Field-of-view: The distance between the target and the measuring device is very important for getting accurate readings with infrared thermometer. This is called the field of view. So you have to see to it that the target is larger than the spot size the unit is measuring. Hence if the target is small, you should get as close as possible for accuracy in measurement.
• Distance from spot ratio: Infrared thermometer operate in a particular style by collecting infrared energy from a circular measurement spot and then focusing it on the detector. It is to be mentioned here that optical resolution is measured as the ratio of the distance from instrument to the object compared to the size of the spot being measured (D: S ratio). Hence, larger the ratio number the better the instrument's resolution and far better would be the accuracy.
• Focus feature: This is comparatively a new feature that has been developed to help in getting accuracy in reading. As per this additional feature you can get accurate measurement of small target areas without including unwanted background temperatures.
Remember all these factors while using infrared thermometer and rest assured you can never fail to obtain the most apt measurements.
