1、熱電偶的分度號必須與所采用溫度測控儀表所要求的熱電偶一致;

2、安裝熱電偶的位置應盡可能離開強電磁場，避開大功率電源線，以免測溫儀表引入附加千擾信號;

3、合理選擇熱電偶外套管的材質、外徑大小
，確保有足夠的強度，並且要適應被測環境氣氛。外套管表麵應保持清潔，表麵汙漬會使熱阻增加
，測量溫度將低於實際溫度;

4、熱(re)電(dian)偶(ou)不(bu)能(neng)長(chang)時(shi)間(jian)在(zai)最(zui)高(gao)允(yun)許(xu)溫(wen)度(du)下(xia)工(gong)作(zuo)，否(fou)則(ze)將(jiang)造(zao)成(cheng)熱(re)電(dian)偶(ou)材(cai)質(zhi)變(bian)化(hua)，導(dao)致(zhi)測(ce)量(liang)誤(wu)差(cha)增(zeng)大(da)。在(zai)測(ce)量(liang)低(di)溫(wen)時(shi)，為(wei)減(jian)小(xiao)熱(re)電(dian)偶(ou)的(de)熱(re)惰(duo)性(xing)，可(ke)采(cai)用(yong)碰(peng)底(di)型(xing)或(huo)露(lu)頭(tou)型(xing)熱(re)電(dian)偶(ou);
