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,。可調(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,，反復調(diào)節(jié)直至儀器穩(wěn)定。上海禹重實業(yè)有限公司分析儀獲得眾多用戶的認可,。江蘇進口分析儀多少錢
