　　pH電極又稱pH探頭、pH傳感器，英文名稱pH electrode或pH sensor，是PH計上與被測物質接觸的部分，通過測電極電位來表征pH值的裝置。pH電極通常有兩種方法測量水相溶液中的pH值，比色法（pH試紙和比色皿）和電位法。其中只有電位法能夠實現連續在線測量和過程監控、且可獲得精確且結果可重復的pH值。pH電極測量的核心理(li)論是(shi)能(neng)斯(si)特方(fang)程(cheng)。

　　一套完整的工業在線pH測量系統，通常由pH傳感器即pH電極、pH顯示(shi)變送器、電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)護套(tao)及電(dian)(dian)(dian)(dian)(dian)纜等四(si)部分(fen)構(gou)成。在線(xian)PH計電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)原理是(shi)電(dian)(dian)(dian)(dian)(dian)位分(fen)析法所用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)被(bei)(bei)稱(cheng)為(wei)原電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。原電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)一(yi)個(ge)系統，它(ta)的(de)(de)(de)作用(yong)是(shi)使化學反(fan)應能量(liang)(liang)轉成為(wei)電(dian)(dian)(dian)(dian)(dian)能。此電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓被(bei)(bei)稱(cheng)為(wei)電(dian)(dian)(dian)(dian)(dian)動勢（EMF）。此電(dian)(dian)(dian)(dian)(dian)動勢（EMF）由二個(ge)半(ban)(ban)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)構(gou)成。其中(zhong)一(yi)個(ge)半(ban)(ban)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)稱(cheng)作測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)，它(ta)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)位與特定的(de)(de)(de)離子活度有關(guan)；另一(yi)個(ge)半(ban)(ban)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)為(wei)參比(bi)(bi)半(ban)(ban)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，通(tong)常稱(cheng)作參比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)，它(ta)一(yi)般(ban)是(shi)與測(ce)量(liang)(liang)溶液相(xiang)通(tong)，并且與測(ce)量(liang)(liang)儀表相(xiang)連。最熟悉也是(shi)常用(yong)的(de)(de)(de)PH指示(shi)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)是(shi)玻(bo)璃(li)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。

　　此外，酸(suan)性條(tiao)件下工作的PH電(dian)極(ji)有：W=5％~10％的熱堿性溶液（>56℃）；W=5％~10％的鹽酸(suan)；W=2％~3％的氫(qing)氟酸(suan)等。

　　總的來說，pH電極在化學研(yan)究和工業生產(chan)中(zhong)具有廣泛的(de)應(ying)用，是(shi)實現精(jing)確pH測(ce)量的(de)關鍵設備。如需更多信息，建議(yi)閱讀相關文(wen)獻或咨詢化學專家。
