值和介質溫度值，具有模擬信號和數(shù)字信號輸出以及控制功能。溶解氧(DO)，是評價水體自凈能力的指標。溶解氧含量較高，表示水體自凈能力強；反之表示水體中污染物不易被氧化分解，此時厭氧性菌類就會大量繁殖，使水質變臭。廣泛應用于工業(yè)、農業(yè)、科研、環(huán)保等領域。</span></span></p><p><span style="font-size:16px"><span

style="font-family:黑體">一臺儀器若能正確地加以維護，對于保證儀器測量精度，延長儀器特別是電極的使用壽命是*的。</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體">對于液晶顯示的電子單元如果發(fā)現(xiàn)故障，請勿擅自拆修，請送回工廠檢查和修理，儀器長久不用時，應將電池取出，以免電池變質毀壞儀器。在現(xiàn)場使用儀器的情況，在較長時間不進行測量時，應關閉電源，取出電池，以延長電池使用壽命。在間斷工作的條件下，電池使用壽命大約24小時。</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體">電極的維護</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體"> 氧電極的維護包括定期更換電解液和薄膜，定期清洗及再生電極。</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體">1、.將電極從儀表上拔下。</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體">2、旋下舊的電極膜套，用蒸餾水沖洗電極的測量端部和電極膜套。</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體">3、如果金陰極呈現(xiàn)暗色，需要用拋光紙進行拋光，在拋光紙上滴一滴去離子水，將金陰極在濕的拋光紙上打圈摩擦5—10圈，磨好后用去離子水沖洗電極以除去殘留物，用紙巾擦干。金陰極在拋光后變得明亮即可。</span></span></p><p><span style="font-size:16px"><span style="font-family:黑體">4、清洗和再生銀陽極方法如下。仔細檢查銀陽極表面，陽極表面通常具有銀灰色的光澤，如果銀陽極表面為黑色，則需用拋光紙輕輕摩擦銀陽極表面，磨好后用去離子水沖洗電極以除去殘留物，用紙巾擦干。</span></span></p><p><span style="font-size:16px"><span
