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(cè)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(wú)電流的參比電極（銀）組成，電極浸沒(méi)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(cè)量的液體分開(kāi)，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(lái)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(cè)量元件浸入在有溶解氧的水中，氧會(huì)通過(guò)隔膜擴(kuò)散，出現(xiàn)在陰極上（電子過(guò)剩）的氧分子就會(huì)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(duì)于每個(gè)氧分子，陰極放出4個(gè)電子，反電極接受電子，形成電流，電流的大小與被測(cè)同污水的氧分壓成正比，該信號(hào)連同傳感器上熱電阻測(cè)出的溫度信號(hào)被送入變送器，利用傳感器中存儲(chǔ)的含氧量和氧分壓、溫度之間的關(guān)系曲線計(jì)算出水中的含氧量，然后轉(zhuǎn)化成標(biāo)準(zhǔn)信號(hào)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(shí)間為：3分鐘后達(dá)到**終測(cè)量值的90%，9分鐘后達(dá)到**終測(cè)量值的99%。極譜法要求每次更換膜或電解液后，必須對(duì)電極進(jìn)行極化。陜西口碑好溶氧儀廠家供應(yīng)</p><p
