氧氮氫分析儀的常見故障及解決方法：氧和氮空白值超過20。這是由于氣流小，不能將爐子中的空氣驅(qū)趕出去?？烧{(diào)節(jié)氣體流量，調(diào)節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣，放一個石墨坩堝在下電極上，打開主電源開關(guān)，點擊軟件上的關(guān)爐按鈕，關(guān)閉爐子并等待10s。調(diào)節(jié)流量調(diào)節(jié)器，直到流量計a顯示為30L／h，打開爐子。調(diào)節(jié)調(diào)節(jié)器直到流量計b顯示為50L／h，再次關(guān)閉爐子。如果以上設(shè)置不穩(wěn)定，則增加流量至100L／h，反復(fù)調(diào)節(jié)直至儀器穩(wěn)定。合肥LECO分析儀采購
