氧化鋯氧量分析儀（又稱氧化鋯氧分析儀、氧化鋯分析儀、氧化鋯氧量計、氧化鋯氧量表），主要用于測量燃燒過程中煙氣的含氧濃度，同樣也適用于非燃燒氣體氧濃度測量。在傳感器內(nèi)溫度恒定的電化學(xué)電池（氧濃差電池，也簡稱鋯頭）產(chǎn)生一個毫伏電勢，這個電勢直接反應(yīng)出煙氣中含氧濃度值。 </p> <p> 氧傳感器的關(guān)鍵部件是氧化鋯，在氧化鋯元件的內(nèi)外兩側(cè)涂上多孔性鉑電極制成氧濃度差電池。它位于傳感器的頂端。為了使電池保持額定的工作溫度，在傳感器中設(shè)置了加熱器。用氧分析儀內(nèi)的溫度控制器控制氧化鋯溫度恒定。 </p> <p> 參比氣體應(yīng)為干燥清潔無油的空氣（含氧20.60％）。在參比氣側(cè)與被測氣體側(cè)氧濃度不同時，氧離子從高的一側(cè)遷移到低的一側(cè)。電池輸出就以對數(shù)的規(guī)律反應(yīng)出被測氣體中的氧濃度值。 </p><p> 氧化鋯分析儀關(guān)于對Zr02-II 氧化鋯氧量分析儀的使用條件 </p> <p> 3.1
