氧(yang)化鋯氧(yang)量(liang)分(fen)析儀(yi)（Zirconia Oxygen Analyzer）又稱氧(yang)(yang)化鋯氧(yang)(yang)分(fen)析儀、氧(yang)(yang)化鋯分(fen)析儀、氧(yang)(yang)化鋯氧(yang)(yang)量(liang)計、氧(yang)(yang)化鋯氧(yang)(yang)量(liang)表，主要用于測量(liang)燃燒過程中(zhong)煙氣的含氧(yang)(yang)濃度，同樣也適用于非可燃性氣體(ti)氧(yang)(yang)濃度測量(liang)。
氧(yang)化鋯氧(yang)量分析儀由氧(yang)(yang)(yang)化鋯氧(yang)(yang)(yang)量(liang)(liang)檢測(ce)器(qi)(俗稱氧(yang)(yang)(yang)探頭(tou)(tou))和氧(yang)(yang)(yang)量(liang)(liang)變送器(qi)組成， 在氧(yang)(yang)(yang)化鋯氧(yang)(yang)(yang)量(liang)(liang)檢測(ce)器(qi)的(de)**元件氧(yang)(yang)(yang)化鋯濃差電池上，采(cai)用(yong)(yong)了納米材料(liao)和良好的(de)生產工藝，在電極(ji)涂(tu)層上添加抑制電極(ji)老化的(de)添加劑。大大提(ti)高了氧(yang)(yang)(yang)化鋯測(ce)量(liang)(liang)探頭(tou)(tou)的(de)精(jing)度和使(shi)用(yong)(yong)壽命。氧(yang)(yang)(yang)量(liang)(liang)檢測(ce)器(qi)采(cai)用(yong)(yong)直插(cha)式探頭(tou)(tou)結構，不需取樣系統，能(neng)及時反映鍋爐內燃燒狀況，如與自控(kong)(kong)裝置配合(he)使(shi)用(yong)(yong)，可(ke)有效地控(kong)(kong)制燃燒狀況。轉換器(qi)采(cai)用(yong)(yong)單片機智(zhi)能(neng)化設計，中文液(ye)晶顯示，使(shi)數據顯示、功能(neng)控(kong)(kong)制更(geng)具有人性化;可(ke)與各(ge)類型(xing) DCS 數據接入設備連接。使(shi)儀(yi)表(biao)的(de)操作(zuo)變得簡單，容易掌握。
