Wehewehe Pōkole:

He mea ʻike ka Thermocouple i hoʻohana ʻia e ana i ka mahana. Loaʻa i nā Thermocouples ʻelua mau wāwae uea i hana ʻia mai nā metala like ʻole. Hoʻopili ʻia nā wāwae uea ma kekahi ʻaoʻao, e hana ana i kahi hui. ʻO kēia hui kahi e ana ʻia ai ka mahana. Ke loli ka mahana o ka hui ʻana, hana ʻia kahi voltage. A laila hiki ke wehewehe ʻia ka voltage me ka hoʻohana ʻana i nā papa kuhikuhi thermocouple e helu ai i ka mahana.
Loaʻa ka hoʻohana nui ʻia ʻana o ka uea thermocouple NiCr-NiAl (ʻAno K) i nā thermocouple metala kumu āpau, ma ka mahana ma luna o 500 °C.
