YSI ProODO光學(xué)溶解氧測(cè)量?jī)x                           

主要特點(diǎn)：                                                 

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

·智能數(shù)字傳感器技術(shù)能將校準(zhǔn)數(shù)據(jù)存儲(chǔ)在傳感器中，探頭即使安裝在任一沒(méi)有校準(zhǔn)過(guò)的ProODO主機(jī)上，也可正常運(yùn)行                                                 

·適配300毫升BOD瓶                                                      

·用戶(hù)可在野外自行更換傳感器                                                       

·IP67防水等級(jí)，電池倉(cāng)與儀器電路倉(cāng)各自獨(dú)立分隔并密封，即使電池倉(cāng)進(jìn)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(zhǎng)                                                  

·存儲(chǔ)2000組數(shù)據(jù)（含傳感器數(shù)據(jù)、日期、時(shí)間、站點(diǎn)和用戶(hù)自定義信息）                    

·借助標(biāo)配的USB線(xiàn)連接ProPlus主機(jī)和計(jì)算機(jī)，不僅能為主機(jī)供電，亦可運(yùn)用易于操作的Data Manager軟件設(shè)置主機(jī)、                                                 

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(cè)量模式：自動(dòng)/手動(dòng)采樣模式/連續(xù)實(shí)時(shí)測(cè)量模式                                                    

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

·用戶(hù)可自選電纜長(zhǎng)度，zui長(zhǎng)可達(dá)100米；電纜整理套件幫助整理4米或更長(zhǎng)的電纜    

·MS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(wàn)次彎折，經(jīng)久耐用                                                

·內(nèi)置氣壓計(jì)                                                       

·超長(zhǎng)保修期：主機(jī)三年，電纜兩年，探頭兩年                                                  

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

·不受流速限制，無(wú)流速或攪拌依賴(lài)性                                                  

·無(wú)需預(yù)熱時(shí)間                                                  

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

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

·更低的維護(hù)量：無(wú)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(guó)YSI維賽 ProODO 系統(tǒng)規(guī)格（主機(jī)、電纜和傳感器）
