溶氧儀闡述儀表采用極譜式電極，陽電極為Ag/AgCl、陰電極為鉑金（Pt）組成，兩者之間充滿特殊成份的是電解液。由硅橡膠滲透膜包裹于電極四周。測量時，電極間加上675mV的極化電壓,氧滲透過隔膜在陰極消耗,同時等量的氧在陽極產(chǎn)生,這個動態(tài)過程進(jìn)行到兩邊的氧分壓相同時達(dá)到平衡.此時兩電極間的電流與氧分壓成正比,二次表檢測到此電流,再經(jīng)過一系列變換,得到氧濃度和氧含量.同時,NTC（負(fù)溫度系數(shù)熱敏電阻）檢測被測量液的溫度,二次表采樣后進(jìn)行溫度補(bǔ)償,將氧濃度或氧含量折算成25℃時的值。溶氧儀描述溶氧儀電極的維護(hù)：(1)1~2周應(yīng)清洗一次溶氧儀電極，如果膜片上有污染物，會引起測量誤差。清洗時應(yīng)小心，注意不要損壞膜片。將溶氧儀電極放入清水中涮洗，如污物不能洗去，用軟布或棉布小心擦洗。(2)2~3月應(yīng)重新校驗一次溶氧儀電極的零點(diǎn)和量程。(3)溶氧儀電極的再生大約1年左右進(jìn)行一次。當(dāng)測量范圍調(diào)整不過來，就需要對溶解氧電極再生。電極再生包括更換內(nèi)部電解液、更換膜片、清洗銀電極。如果觀察銀電極有氧化現(xiàn)象，可用細(xì)砂紙拋光。(4)在使用中如發(fā)現(xiàn)溶氧儀電極泄露，就必須更換電解液。參考以上所說的，溶氧儀買回來的使用不光是要使用的正確，重要的是維護(hù)方面。而極譜法使用前必須進(jìn)行極化，但無需頻繁維護(hù)，特別適用于連續(xù)過程的在線分析。江蘇原裝溶氧儀承諾守信</p><p style="text-indent:25px">溶氧儀（Dissolved oxygen analyzer ）是根據(jù)電化學(xué)原理。福建溶氧儀貨源充足</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(hù)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(kuò)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)到最終測量值的90%，9分鐘后達(dá)到最終測量值的99%。福建溶氧儀貨源充足</p><p
