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)到最終測(cè)量值的90%，9分鐘后達(dá)到最終測(cè)量值的99%。</p><p> 溶氧是水產(chǎn)養(yǎng)殖中的一個(gè)十分重要的水質(zhì)指標(biāo)。當(dāng)水體缺氧時(shí)，魚(yú)類(lèi)生產(chǎn)速度變慢。嚴(yán)重的，會(huì)出現(xiàn)浮頭、死亡等。溶氧不僅是水生動(dòng)物呼吸作用必須的，也是水中有機(jī)物分解、浮游生物生長(zhǎng)的必備條件。在水產(chǎn)養(yǎng)殖中，除了必要的增氧措施外，及時(shí)、準(zhǔn)確、方便地監(jiān)測(cè)水體的溶氧值也是十分重要的。曾經(jīng)出現(xiàn)過(guò)暴風(fēng)雨的晚上，養(yǎng)殖戶摸黑開(kāi)電閘被電亡的悲劇。因此，水質(zhì)在線檢測(cè)物聯(lián)網(wǎng)系統(tǒng)便于應(yīng)運(yùn)而生了。在線水質(zhì)檢測(cè)物聯(lián)網(wǎng)通過(guò)高靈敏度的在線水質(zhì)探頭，將數(shù)據(jù)傳輸給主機(jī)。再通過(guò)無(wú)線發(fā)射模塊，將數(shù)據(jù)及時(shí)準(zhǔn)確地上傳到遠(yuǎn)程終端上（手機(jī)、電腦等）。使管理都無(wú)論在哪里，都可以及時(shí)準(zhǔn)確地知道水產(chǎn)養(yǎng)殖池塘中的水質(zhì)數(shù)據(jù)。同時(shí)，可以在主機(jī)上提前設(shè)置。當(dāng)水體的溶氧值高于設(shè)置值時(shí)，主機(jī)可通過(guò)控制器停止增氧機(jī)，以節(jié)省電耗。當(dāng)水中的溶氧低于設(shè)置值時(shí)，主機(jī)可自動(dòng)開(kāi)啟增氧機(jī)。使用這種方式后，可以節(jié)省大量的成本。在線水質(zhì)檢測(cè)物聯(lián)網(wǎng)系統(tǒng)包括主機(jī)、信號(hào)傳輸模塊、控制器、探頭、數(shù)據(jù)接收終端等。探頭采用目前領(lǐng)先技術(shù)的熒光法檢測(cè)探頭。使用更加簡(jiǎn)單、檢測(cè)數(shù)據(jù)更加精確，使用壽命也持久。在線水質(zhì)檢測(cè)物聯(lián)網(wǎng)系統(tǒng)的檢測(cè)指標(biāo)包括：溶解氧、PH、溫度、ORP等。可根據(jù)客戶需求。也有的儀器采用伏安測(cè)定中的極譜法，對(duì)溶液中的工作電極施加電壓。</p><div

-介紹：全新一代哈希LDO?II溶解氧傳感器，基于熒光猝熄原理進(jìn)行溶解氧的測(cè)定。不同于傳統(tǒng)的電流法和極譜法溶解氧傳感器，熒光法溶解氧傳感器不使用膜和電解液，維護(hù)率低，操作簡(jiǎn)便；同時(shí)熒光法溶解氧傳感器不消耗氧氣，測(cè)定時(shí)對(duì)水樣流速和攪拌沒(méi)有要求，也不受硫化物等物質(zhì)的干擾，讓溶解氧的測(cè)定變得更加簡(jiǎn)單。-工作原理：LDO?II溶解氧傳感器基于熒光猝熄原理。藍(lán)光照射到熒光物質(zhì)上激發(fā)出紅光，由于氧分子可以帶走能量，所以激發(fā)的紅光的時(shí)間和強(qiáng)度與氧分子的濃度成反比。溶解氧測(cè)定儀通過(guò)測(cè)量激發(fā)紅光與參比光的相位差，并與內(nèi)部標(biāo)定值對(duì)比，從而可計(jì)算出氧分子的濃度。-典型應(yīng)用：LDO?II溶解氧傳感器適用于污水、工業(yè)用水、飲用水等行業(yè)溶解氧的測(cè)定。-特性和優(yōu)點(diǎn)：●無(wú)需校準(zhǔn)哈希LDO?II溶解氧傳感器出廠前已完成校準(zhǔn)，開(kāi)箱即用，無(wú)需校準(zhǔn)，熒光帽使用壽命長(zhǎng)達(dá)兩年?！駸o(wú)需更換膜片采用哈希公司突破性的熒光技術(shù)，該溶解氧傳感器基本無(wú)需維護(hù)，因?yàn)橐褵o(wú)需更換膜片，也不用補(bǔ)充電解質(zhì)溶液，更無(wú)需對(duì)陽(yáng)極和陰極進(jìn)行打磨清潔?！穹?wù)無(wú)遺漏該溶解氧傳感器具有可自定義的清洗服務(wù)提示功能，在溶解氧的測(cè)定過(guò)程中到時(shí)自動(dòng)觸發(fā)服務(wù)提示消息。由于該法可直接將待測(cè)參數(shù)轉(zhuǎn)換成電信號(hào)，測(cè)試響應(yīng)靈敏，便于實(shí)現(xiàn)連續(xù)在線分析，因而應(yīng)用十分***。福建直銷(xiāo)溶氧儀</p><p
