-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；同時熒光法溶解氧傳感器不消耗氧氣，測定時對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，并與內(nèi)部標(biāo)定值對比，從而可計算出氧分子的濃度。-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：●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)，因為已無需更換膜片，也不用補(bǔ)充電解質(zhì)溶液，更無需對陽極和陰極進(jìn)行打磨清潔?！穹?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自動觸發(fā)服務(wù)提示消息。上海環(huán)保局溶氧儀將探頭放入被測溶液中，同時需要攪絆。</p><div
