class="NyNewsdetail_con"> <div>　　便攜式多參數(shù)水質(zhì)分析儀采用光電子比色檢測原理取代傳統(tǒng)的目視比色法，消除了人為誤差，測量分辨率大大提高。測量時，當被測水樣放入特定試劑時，水樣會迅速顯色。然后將此水樣放入光電比色座內(nèi)，儀器多參數(shù)水質(zhì)分析儀可適用于大、中、小型水廠及工礦企業(yè)、游泳池等地的生活或工業(yè)用水中的離子濃度檢測，以便控制水的各項參數(shù)達到規(guī)定的水質(zhì)標準要求。</div><div> </div><div>　　目前，本產(chǎn)品廣泛應用于工業(yè)、農(nóng)業(yè)、醫(yī)藥、科研機構等行業(yè)。能對煙草、造紙、食品、茶葉、飼料、谷物、化工原料、制藥原料、紡織原料等樣品所含的游離水份進行含量測試及數(shù)據(jù)打印。</div><div> </div><p align="center"><img

</p><div>　　它的操作步驟：</div><div>　　1、打開便攜式多參數(shù)水質(zhì)分析儀箱體，做檢測前的準備工作。使用前需要洗干凈比色皿的外表和內(nèi)里，實驗室有條件的可以使用超聲波清洗機清洗30min，如果不具備這個條件，也可以用洗潔精洗，洗完之后用純水沖洗干凈，后使用軟布將比色皿的水跡和指紋擦拭干凈。</div><div>　　2、打開電源開關，通過按鍵選擇到色度的校零選項。在選擇小號的比色皿，加入純水至小號比色皿的刻度線處，并用軟布將比色皿表面的水跡和指紋擦干凈。</div><div>　　3、開始儀器的校零，待比色皿放置到儀器內(nèi)，蓋好蓋，等待3s以后開始校零。</div><div>　　4、待校零結(jié)束以后，將比色皿內(nèi)的純水倒掉，擦拭干凈。使用本產(chǎn)品時，加入待檢測水樣10ml到反應瓶；使用手持式九項便攜式多參數(shù)水質(zhì)分析儀時，加入待檢測水樣10ml到圓形比色瓶。并用軟布將比色皿表面的水跡和指紋擦干凈。</div><div>　　5、加入氨氮試劑Ⅰ4滴到反應瓶或圓形比色瓶，蓋上蓋子，搖勻。</div><div>　　6、再加氨氮試劑Ⅱ4滴到反應瓶或圓形比色瓶，蓋上蓋子，搖勻。</div><div>　　7、靜置反應5min。</div><div>　　8、待反應*后把反應后的水樣倒入小號比色皿刻度線處。用軟布將比色皿表面的水跡和指紋擦干凈。</div><div>　　9、將裝有水樣的比色皿放置進便攜式多參數(shù)水質(zhì)分析儀中，蓋好蓋，3s后開始檢測，等待幾秒，儀器會直接顯示結(jié)果。如果需要打印，可以直接在儀器上打印出來。</div><div>　　10、所有項目檢測完畢之后，關閉電源。將比色皿取出，將水樣倒掉，用純水清洗干凈比色面的外表和內(nèi)里。洗完之后用軟布或者紙巾將比色皿擦拭干凈，并將比色皿妥善安放。</div>
