Wayar thermocouple tana ba da damar auna yanayin zafi ta hanyar lantarki. Tsarin thermocouple na yau da kullun ya ƙunshi ƙarfe biyu daban-daban waɗanda aka haɗa ta hanyar lantarki a wurin ji kuma an haɗa su da na'urar auna ƙarfin lantarki a ɗayan ƙarshen. Lokacin da mahaɗin ɗaya ya fi ɗayan zafi, ana samar da ƙarfin "electromotive" na zafi (a cikin millivolts) wanda yayi daidai da bambancin zafin jiki tsakanin mahaɗin zafi da sanyi.

NiCr-NiSi (Nau'in K)Wayar thermocoupleYana samun mafi yawan amfani a cikin dukkan thermocouple na ƙarfe, a zafin da ya wuce 500 °C.
Wayar thermocouple ta Type K tana da ƙarfin juriya ga iskar shaka fiye da sauran na'urorin thermocouple na ƙarfe. Tana da babban EMF akan Platinum 67, kyakkyawan daidaiton zafin jiki, kulawa da kwanciyar hankali, tare da ƙarancin farashi. Ana ba da shawarar yin amfani da ita don iskar shaka ko yanayin da ba ya aiki, amma ba za a iya amfani da ita kai tsaye a cikin waɗannan yanayi ba:
(1) A madadin haka, yana ƙara iskar oxygen da rage yanayi.
(2) Yanayi mai iskar sulfur.
(3) Tsawon lokaci a cikin injin tsabtace iska.
(4) Yanayin da ke ƙaranci iskar oxygen kamar hydrogen da carbon monoxide.
