Txoj cai Angle thermocouples feem ntau yog siv rau hauv cov ntawv thov uas qhov kev teeb tsa kab rov tav tsis haum, lossis qhov chaw kub thiab cov pa phem raug ntsuas, thiab cov qauv sib xws yog hom K thiab E. Tau kawg, lwm cov qauv kuj tuaj yeem hloov kho. Feem ntau yog siv rau hauv metallurgy, tshuaj lom neeg kev lag luam, tsis-ferrous hlau smelting, tshwj xeeb tshaj yog haum rau cov kua txhuas, kua tooj liab ntsuas kub, vim nws qhov siab ceev, ntsuas kub txheej txheem tsis corroded los ntawm kua txhuas; Zoo thermal poob siab tsis kam, rwb thaiv tsev tsis kam rau oxidation, kub thiab hnav tsis kam, kev pab lub neej ntev.
