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(rèn)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(xué)試劑，如果有空氣進入熱導(dǎo)池里,，熱導(dǎo)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(dǎo)池電壓值必然升高。經(jīng)過逐一排查,，**終確認(rèn)堿石棉有問題,，更換后儀器正常。上海禹重實業(yè)有限公司為您提供分析儀,，期待您的光臨,！
