最近流感爆發, 公司買了一支射額式的探熱器

雖然知道額頭的溫度會低1-2度, 但奇怪是
平均溫度通常34度而已, 有時全公司都一下子跳到35.5

問題是公司裡的空氣會不會影響探熱器的準確性?

例如二氧化碳濃度, 或者空氣的溫度

Although an infrared thermometer is unidirectional, it inevitably detect infrared from neaby sources.

If the measured temperatures are consistently increased, it may be due to the presence of some heat sources, e.g. incandescent light bulbs, photocopying machines, printers etc. that contribute to the ambient infrared radiation.
