<div>　　酸堿濃度計和pH計存在多方面區(qū)別，具體如下：</div><div>　　</div><div>　　一、測量原理</div><div>　　</div><div>　　酸堿濃度計：基于電導(dǎo)率原理，通過測量溶液的電導(dǎo)率來確定酸堿濃度。在某一穩(wěn)定溫度下，低濃度電解質(zhì)的電導(dǎo)率與該溶液的濃度成對應(yīng)關(guān)系，儀表產(chǎn)生高穩(wěn)定度的方波信號加在電導(dǎo)池上，流過電導(dǎo)池的電流與被測溶液的濃度成正比，經(jīng)運(yùn)算和溫度補(bǔ)償后得到濃度值。</div><div>　　</div><div>　　pH計：利用pH指示電極以電位法測定溶液pH值。將pH指示電極和參比電極浸在溶液中構(gòu)成測量電池，所產(chǎn)生的電動勢與溶液的pH值有關(guān)，通過測量原電池的電動勢，進(jìn)而計算出溶液的pH值。</div><div>　　</div><div>　　二、測量對象</div><div>　　</div><div>　　酸堿濃度計：主要用于測量溶液中的酸或堿的濃度，通常以質(zhì)量百分比濃度等來表示，如硫酸、鹽酸、氫氧化鈉等的濃度。<br /><br /> </div><p style="text-align: center;"><img src="https://img58.chem17.com/9/20250225/638760933398586437116.jpg" alt="酸堿濃度計" width="600" align="middle" height="589" /></p><p> </p><div>　　</div><div>　　pH計：測量的是溶液的酸堿度，即pH值，用來衡量溶液中氫離子的活度，范圍一般在0-14之間。</div><div>　　</div><div>　　三、顯示結(jié)果</div><div>　　</div><div>　　酸堿濃度計：直接顯示酸或堿的濃度數(shù)值及對應(yīng)的溫度值。</div><div>　　</div><div>　　pH計：顯示的是pH值，部分pH計還可顯示溫度、電極電位等相關(guān)信息。</div><div>　　</div><div>　　四、應(yīng)用領(lǐng)域</div><div>　　</div><div>　　酸堿濃度計：廣泛應(yīng)用于火電、化工、鋼鐵酸洗等行業(yè)，對水溶液中的化學(xué)酸或堿濃度進(jìn)行連續(xù)檢測和控制，例如電廠對離子交換樹脂的再生過程監(jiān)測。</div><div>　　</div><div>　　pH計：適用于電力、農(nóng)業(yè)、醫(yī)藥、食品、科研和環(huán)保等眾多領(lǐng)域，是食品廠、飲用水廠辦QS、HACCP認(rèn)證中的檢驗設(shè)備。</div><div>　　<br

</p><div>　　五、儀器構(gòu)造</div><div>　　</div><div>　　酸堿濃度計：一般由傳感器、前置放大器、微處理器、顯示器等部分組成，結(jié)構(gòu)相對簡單，部分還帶有自動清洗功能。</div><div>　　</div><div>　　pH計：主要由電極、主機(jī)組成，電極包括pH玻璃膜電極、參比電極等，主機(jī)內(nèi)有放大器、模數(shù)轉(zhuǎn)換器等電路元件，對電極要求較高。</div><div>　　</div><div>　　酸堿濃度計和pH計在測量原理、測量對象、顯示結(jié)果、應(yīng)用領(lǐng)域以及儀器構(gòu)造方面均有所不同。用戶可根據(jù)實(shí)際需求選擇合適的儀器進(jìn)行測量。</div>
