工作原理：<\/span><\/p>\r 氨氮監(jiān)測(cè)儀管路充滿(mǎn)水樣后，<\/span>其p<\/span>H值被測(cè)定。<\/span>加入氫氧化鈉試劑后，<\/span>pH值升到10.5–<\/span>10.9。<\/span>當(dāng)水樣的pH值大于9時(shí)，<\/span>水樣中待測(cè)的銨離子轉(zhuǎn)化為氣態(tài)的氨。<\/span>這時(shí)利用氨氣敏電 極測(cè)量氨氮值，就可以直接獲得水樣中氨氮的濃度，通過(guò)pH電<\/span>極測(cè)量的值來(lái)控制加入氫氧 化鈉試劑的量，溫度電極在氨氮測(cè)量過(guò)程中<\/span>對(duì)溫度做出補(bǔ)償后修正最終得出測(cè)量值，方程式<\/span><\/span>如下：<\/span>NH <\/span><\/em>+<\/span>⎯<\/span>⎯<\/span>pH<\/span><\/span><\/em>⎯<\/span>><\/span>9<\/span>→<\/span>NH<\/span><\/em><\/span><\/p>\r <\/span><\/p>\r\r <\/span><\/span><\/p>\r <\/span><\/span>儀器特點(diǎn)：<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r 氨氮在線(xiàn)分析儀是測(cè)量水中氨氮值。<\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>氨氣敏電極法<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>儀器內(nèi)設(shè)空壓機(jī)自吸水樣直接測(cè)量<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>無(wú)需水樣品預(yù)處理系統(tǒng)<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>測(cè)量精度高<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>用戶(hù)自行配制試劑，運(yùn)行成本低<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>操作簡(jiǎn)單，維護(hù)方便<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>所用化學(xué)試劑無(wú)二次污染，無(wú)任何有害化學(xué)物質(zhì)<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>測(cè)量管徑32毫米，不易堵塞<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>獨(dú)立封閉電器控制系統(tǒng)，不會(huì)腐蝕<\/span><\/span><\/p>\r <\/span><\/span><\/p>\r *<\/span> <\/span><\/span>2毫米優(yōu)質(zhì)噴塑鋼板機(jī)柜，不易腐蝕<\/span><\/span><\/p>\r <\/span><\/span> *<\/span> <\/span><\/span>儀器機(jī)柜尺寸統(tǒng)一，美觀(guān)，易布置<\/span><\/span><\/p>\r 技術(shù)參數(shù)<\/span><\/p>\r <\/span><\/span><\/p>\r <\/span><\/span><\/p>\r 型號(hào)<\/span><\/p>\r<\/td>\r AMMONO-L<\/span>AB<\/span><\/span><\/p>\r<\/td>\r<\/tr>\r 測(cè)量介質(zhì)<\/span><\/p>\r<\/td>\r 市政污水，工業(yè)廢水，地表水<\/span><\/p>\r<\/td>\r<\/tr>\r 原理<\/span><\/p>\r<\/td>\r 氨氣敏電極法<\/span><\/p>\r<\/td>\r<\/tr>\r 測(cè)量范圍<\/span><\/p>\r<\/td>\r 0~2000mg/LNH<\/span><\/span>4<\/span>-N(可自由設(shè)定)<\/span><\/span><\/p>\r<\/td>\r<\/tr>\r 分辯率<\/span><\/p>\r<\/td>\r ±0.01mg/L<\/span><\/p>\r<\/td>\r<\/tr>\r 測(cè)量周期<\/span><\/p>\r<\/td>\r 連續(xù)在線(xiàn)測(cè)量/0~1440<\/span>分鐘自選設(shè)定<\/span><\/span><\/p>\r<\/td>\r<\/tr>\r 測(cè)量精度<\/span><\/p>\r<\/td>\r 滿(mǎn)量程±5%<\/span><\/p>\r<\/td>\r<\/tr>\r 重復(fù)性<\/span><\/p>\r<\/td>\r 滿(mǎn)量程±2.5%<\/span><\/p>\r<\/td>\r<\/tr>\r 輸出<\/span><\/p>\r<\/td>\r 4~20mA、繼電器報(bào)警、錯(cuò)誤代碼顯示<\/span><\/p>\r<\/td>\r<\/tr>\r 數(shù)據(jù)儲(chǔ)存<\/span><\/p>\r<\/td>\r 2500組數(shù)<\/span>據(jù)，電池保存<\/span><\/p>\r<\/td>\r<\/tr>\r 最大負(fù)載<\/span><\/p>\r<\/td>\r 350歐姆<\/span><\/p>\r<\/td>\r<\/tr>\r 數(shù)據(jù)顯示<\/span><\/p>\r<\/td>\r LED顯示<\/span><\/p>\r<\/td>\r<\/tr>\r 通信接口<\/span><\/p>\r<\/td>\r RS232<\/span><\/p>\r<\/td>\r<\/tr>\r 校正<\/span><\/p>\r<\/td>\r 24小時(shí)/次的循環(huán)自動(dòng)校正，也可手動(dòng)校正<\/span><\/p>\r<\/td>\r<\/tr>\r 水樣進(jìn)出水管徑<\/span><\/p>\r<\/td>\r 32mm PV<\/span>C管<\/span><\/p>\r<\/td>\r<\/tr>\r 取樣方式<\/span><\/p>\r<\/td>\r 自吸<\/span><\/p>\r<\/td>\r<\/tr>\r 吸樣高度<\/span><\/p>\r<\/td>\r 最大5m<\/span><\/p>\r<\/td>\r<\/tr>\r 樣品量<\/span><\/p>\r<\/td>\r 0.4升/次<\/span><\/p>\r<\/td>\r<\/tr>\r 工作溫度<\/span><\/p>\r<\/td>\r +4~+45℃<\/span><\/p>\r<\/td>\r<\/tr>\r |
