氧氮氫分析儀的常見故障及解決方法供電正常、通訊正常，點擊確認鍵后分析儀不工作。這是沒有水流，爐子溫度太高或儀器通道電壓不正常。如沒有水流，爐子溫度太高這些信息會顯示在顯示器畫面上，但沒有信息顯示說明這兩項正常。接下來檢查儀器通道零位電壓，如果比±3V高出1V以上，可能是因為氣瓶空了，或者是空氣進入到分析儀中。檢查并更換化學試劑，如果有空氣進入熱導池里，熱導池的電壓就會＜-6V，此時打開右面的門，堵住爐子氣體進口，10s后，熱導池電壓值必然升高。經過逐一排查，**終確認堿石棉有問題，更換后儀器正常。上海禹重實業有限公司為您提供分析儀，歡迎新老客戶來電！松江分析儀

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趕出去。可調節氣體流量，調節載氣壓力在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，點擊軟件上的關爐按鈕，關閉爐子并等待10s。調節流量調節器，直到流量計a顯示為30L／h，打開爐子。調節調節器直到流量計b顯示為50L／h，再次關閉爐子。如果以上設置不穩定，則增加流量至100L／h，反復調節直至儀器穩定。分析儀，就選上海禹重實業有限公司，讓您滿意，歡迎您的來電！松江分析儀
