Photovoltaic na'urorin gyarawa zafin jiki na 600 - 4000, da kuma na gani pyrometers godiya karatu cikin 700 - 6000 digiri.

Halitta, tambaya taso na yadda da jiki Properties damar domin ji daga iska zafin jiki da kuma zafi karfe. A gauges dalilin shan da karfi na matsin lamba gas ko ruwa a wasu yanayin zafi. Pyrometers da imagers damar kimantawa da zazzabi da batun surface gabansa emanating daga shi zafi radiation (pyrometers nuna bayanai a cikin digital form, da imager jimloli wani "hoto" daga cikin abu da kuma ta da zazzabi). Amfani da thermoelectric sakamako ne a thermocouple kayayyaki. By kuma manyan, da thermocouple ne rufaffiyar lantarki hanyar biyu daban-daban conductors. Kaddamarda thermal sakamako sa wasu irin ƙarfin lantarki. A irin wannan manufa da ake amfani a juriya thermometers.

A general, da zazzabi da aunawa da hanyoyin za a iya raba lamba kuma ba-lamba. Mai sararin misali lamba Hanyar - likita ma'aunin zafi da sanyio, wadanda ba lamba - thermal imager.
