-介紹：全新一代溶解氧傳感器，基于熒光猝熄原理進(jìn)行溶解氧的測定。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，操作簡便；同時(shí)熒光法溶解氧傳感器不消耗氧氣，測定時(shí)對(duì)水樣流速和攪拌沒有要求，也不受硫化物等物質(zhì)的干擾，讓溶解氧的測定變得更加簡單。-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。溶解氧測定儀通過測量激發(fā)紅光與參比光的相位差，陜西質(zhì)量溶氧儀質(zhì)量商家，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)溶解氧的測定。-特性和優(yōu)點(diǎn)：●無需校準(zhǔn)哈希LDO?II溶解氧傳感器出廠前已完成校準(zhǔn)，開箱即用，無需校準(zhǔn)，熒光帽使用壽命長達(dá)兩年?！駸o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需維護(hù)，陜西質(zhì)量溶氧儀質(zhì)量商家，因?yàn)橐褵o需更換膜片，陜西質(zhì)量溶氧儀質(zhì)量商家，也不用補(bǔ)充電解質(zhì)溶液，更無需對(duì)陽極和陰極進(jìn)行打磨清潔。●服務(wù)無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，在溶解氧的測定過程中到時(shí)自動(dòng)觸發(fā)服務(wù)提示消息。測量前用飽和濕空氣（或平衡水）對(duì)溶氧儀進(jìn)行標(biāo)定。陜西質(zhì)量溶氧儀質(zhì)量商家</p><div

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)，魚類生產(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)測水體的溶氧值也是十分重要的。曾經(jīng)出現(xiàn)過暴風(fēng)雨的晚上，養(yǎng)殖戶摸黑開電閘被電亡的悲劇。因此，水質(zhì)在線檢測物聯(lián)網(wǎng)系統(tǒng)便于應(yīng)運(yùn)而生了。在線水質(zhì)檢測物聯(lián)網(wǎng)通過高靈敏度的在線水質(zhì)探頭，將數(shù)據(jù)傳輸給主機(jī)。再通過無線發(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**技術(shù)的熒光法檢測探頭。使用更加簡單、檢測數(shù)據(jù)更加精確，使用壽命也持久。在線水質(zhì)檢測物聯(lián)網(wǎng)系統(tǒng)的檢測指標(biāo)包括：溶解氧、PH、溫度、ORP等?？筛鶕?jù)客戶需求。</p><p>
