Fe/CuNi Hom J Thermocouple Alloy Liab Qab Hlau

Kev piav qhia txog khoom

Hom J Thermocouple feem ntau siv rau nws tus nqi qis thiab EMF siab Nws tuaj yeem siv rau hauv cov xwm txheej oxidizing txog li 760 ° C. Rau qhov kub siab dua, nws raug pom zoo kom siv cov xov hlau loj.
Hom J thermocouple yog tsim rau oxidizing, txo cov huab cua inert lossis lub tshuab nqus tsev.
