多用于實驗室一般分析，注意使用中應(yīng)頻繁應(yīng)進行維護保養(yǎng)。而極譜法使用前必須進行極化，但無需頻繁維護，特別適用于連續(xù)過程的在線分析。折疊編輯本段溶氧儀的標(biāo)定測量前用飽和濕空氣(或平衡水)對溶氧儀進行標(biāo)定。若測量值與用亨利定律計算的理論值相吻合，則可以使用，否則應(yīng)進行檢查。用亨利定律計算出常見壓力、溫度范圍內(nèi)的水中氧飽和溶解度。折疊編輯本段溶氧儀的極化極譜法要求每次更換膜或電解液后，必須對電極進行極化。所謂極化，就是去除極譜室內(nèi)電解液中殘存的溶解氧，使溶解氧向陰極表面遷移時產(chǎn)生的"本底電流"減小到零。這時，為通過原點的直線，所以極化又稱為調(diào)零點。具體做法是將電極放入現(xiàn)配制的無氧水溶液(mol·L硼砂水溶液與無水亞***鈉配成1%~2%亞***鈉溶液)，約10min即可。折疊編輯本段使用方法折疊初次使用(1)裝入電池，將氧探頭與溫度探頭插在儀表上。(2)準(zhǔn)備一杯清水，在空氣中靜置數(shù)小時，使其成為飽和氧水溶液。(3)將氧探頭與溫度探頭同時插入飽和氧水溶液中，約10min使其極化。(4)探頭一直保持連接狀態(tài)，不再需要極化操作，關(guān)閉儀表不受影響。折疊測量(1)按ON鍵打開儀表。(2)將兩探頭同時插入飽和氧水溶液中，并保持溶液流動，若不流動。</p><p>

水溶解氧的能力就越大，其關(guān)系由亨利（Henry）定律和道爾頓（Dalton）定律確定，亨利定律認(rèn)為氣體的溶解度與其分壓成正比。以COS4氧量測量傳感器為例，其中的電極由陰極（常用金和鉑制成）和帶電流的反電極（銀）、無電流的參比電極（銀）組成，電極浸沒在電解質(zhì)如KCl、KOH中，傳感器有隔膜覆蓋，隔膜將電極和電解質(zhì)與被測量的液體分開，因此保護了傳感器，既能防止電解質(zhì)逸出，又可防止外來物質(zhì)的侵入而導(dǎo)致污染和毒化。相反電極和陰極之間施加極化電壓，假如測量元件浸入在有溶解氧的水中，氧會通過隔膜擴散，出現(xiàn)在陰極上（電子過剩）的氧分子就會被還原成氫氧根離子：O2+2H2O+4e-?4OH-。電化學(xué)當(dāng)量的氯化銀沉淀在反電極上（電子不足）：4Ag+4Cl-?4AgCl+4e-。對于每個氧分子，陰極放出4個電子，反電極接受電子，形成電流，電流的大小與被測同污水的氧分壓成正比，該信號連同傳感器上熱電阻測出的溫度信號被送入變送器，利用傳感器中存儲的含氧量和氧分壓、溫度之間的關(guān)系曲線計算出水中的含氧量，然后轉(zhuǎn)化成標(biāo)準(zhǔn)信號輸出。參比電極的功能是確定陰極電位。COS4溶氧傳感器的響應(yīng)時間為：3分鐘后達(dá)到**終測量值的90%，9分鐘后達(dá)到**終測量值的99%。河北原裝溶氧儀</p><p
