YSI ProODO光學溶解氧測量儀                           

主要特點：                                                 

·測量范圍（0-500％）較其它品牌光學溶解氧傳感器更寬廣                                                      

·智能數(shù)字傳感器技術(shù)能將校準數(shù)據(jù)存儲在傳感器中，探頭即使安裝在任一沒有校準過的ProODO主機上，也可正常運行                                                 

·適配300毫升BOD瓶                                                      

·用戶可在野外自行更換傳感器                                                       

·IP67防水等級，電池倉與儀器電路倉各自獨立分隔并密封，即使電池倉進水也不影響或損壞儀器電路                                                   

·外敷橡膠的防滑澆注外殼，抓握更容易，使用壽命更長                                                  

·存儲2000組數(shù)據(jù)（含傳感器數(shù)據(jù)、日期、時間、站點和用戶自定義信息）                    

·借助標配的USB線連接ProPlus主機和計算機，不僅能為主機供電，亦可運用易于操作的Data Manager軟件設(shè)置主機、                                                 

管理分析數(shù)據(jù)以及查看圖形數(shù)據(jù)與表格數(shù)據(jù)                                                  

·兩種測量模式：自動/手動采樣模式/連續(xù)實時測量模式                                                    

·夜光鍵盤和背景光顯示屏便于在昏暗環(huán)境下操作                                                       

·用戶可自選電纜長度，zui長可達100米；電纜整理套件幫助整理4米或更長的電纜    

·MS軍方接頭，快速插拔，防水，連接可靠穩(wěn)固                                                

·接頭的電纜部分可耐受30萬次彎折，經(jīng)久耐用                                                

·內(nèi)置氣壓計                                                       

·超長保修期：主機三年，電纜兩年，探頭兩年                                                  

光學溶解氧傳感器所具有的優(yōu)勢：                                                       

·不受流速限制，無流速或攪拌依賴性                                                  

·無需預熱時間                                                  

·低漂移和長期穩(wěn)定，不必經(jīng)常校準                                                       

·不受硫化氫或其它氣體的影響                                                       

·更低的維護量：無需清潔電極、更換溶液，只需一年更換一次敏感元件                           

技術(shù)參數(shù)：美國YSI維賽 ProODO 系統(tǒng)規(guī)格（主機、電纜和傳感器）
