Abstract

Temperature measurement devices such as thermal imagers routinely have claimed temperature resolutions of 0.1 ⁰C, in fact many high-end devices claim a temperature resolution of 0.02 ⁰C. Yet in the same data sheet, device accuracy is often ten times or even a hundred times higher, often at 2 ⁰C. This apparent discrepancy has been a source of confusion to users of such devices so here we discuss the difference between resolution, accuracy and uncertainty. Note that although the discussion is given in the context of thermal imagers the arguments can be applied quite generally to any measurement device.
