class="NyNewsdetail_tips">更新時間：2023-07-03 點擊次數(shù)：848</div> <div id="tq6ztn8r" class="NyNewsdetail_con"> <div>　　<strong>COD-H8000 COD在線監(jiān)測儀</strong>是一種新型的用于測量污水化學(xué)需氧量的全自動在線分析儀，采用的光電計量、高溫高壓消解、消解比色一體化等技術(shù)，具有測量準(zhǔn)確、檢出限低、可靠性高、適應(yīng)性強等特點。<br /> </div><div>　　<strong>COD在線監(jiān)測儀</strong>的注意事項：</div><div> </div><div>　　1、日常檢查：主要包括檢查COD在線監(jiān)測儀是否正常工作，如進出水管路是否通暢，檢查是否有泄漏，保持儀器清潔，尤其是轉(zhuǎn)動部件和易損件要及時檢查。定期檢查和更換，以防止泄漏損壞儀器和腐蝕儀器。<br /> </div><div>　　2、更換試劑：重鉻酸鉀和硫酸銀是強腐蝕性試劑，在工作現(xiàn)場易揮發(fā)吸潮，應(yīng)定期更換。更換周期視使用情況而定，一般至少3個月一次。<br /> </div><div>　　3、保護性維護：由于蠕動泵管吸收強腐蝕性試劑，應(yīng)每3個月更換一次。測量室和反應(yīng)室應(yīng)至少每年一次進行檢查、清潔和檢修。<br /> </div><div>　　4、日常校準(zhǔn)：除程序設(shè)定的自動調(diào)零循環(huán)校準(zhǔn)外，第一次使用、更換試劑或保護性維護后應(yīng)進行調(diào)零和標(biāo)準(zhǔn)溶液校準(zhǔn)。使用實驗室配制的蒸餾水作為調(diào)零液。校準(zhǔn)過程與測量循環(huán)過程相同。校準(zhǔn)后保留新零點參數(shù)，校準(zhǔn)工作曲線。<br /> </div><div>　　5、安裝環(huán)境：保證COD在線監(jiān)測儀安裝現(xiàn)場的溫度和濕度恒定，必要時安裝空調(diào)等加熱、冷卻和除濕設(shè)施。同時使用獨立的穩(wěn)壓電源。<br /> </div><div>　　6、儀器的暫停：COD在線監(jiān)測儀暫停時，應(yīng)用蒸餾水清洗干凈，然后倒空，然后依次關(guān)閉進、出口閥門和電源。</div> </div> <div id="tq6ztn8r" class="ly_PrevNext"> <ul> <li>上一篇：<a
