pH值的測量pH試紙或指示劑會隨著pH值的變化而改變顏色，可用于粗略地指示pH值。這些指示劑在準確度上存在一定限制，難以通過顏色或模糊的樣本正確指示pH值?！皃H”一詞**什么意思？術(shù)語pH中的“p”來源于表示負對數(shù)的數(shù)學符號“p”，而“H”來源于氫元素的化學符號。更準確的測量需要采用pH計來完成。pH測量系統(tǒng)由三部分組成：pH測量電極，參比電極和高輸入阻抗計。pH電極可當做一個電池，其電壓會隨著被測溶液的pH值變化而變化。pH值測量電極是一個對氫離子敏感的玻璃球，其毫伏級的輸出會隨著玻璃球內(nèi)外的相對氫離子濃度變化而發(fā)生改變。而參考電極的輸出并不會因為氫離子活度的變化而改變。pH電極具有非常高的內(nèi)阻，因此難以測量pH值所導致的電壓變化。所以，pH計的輸入阻抗和漏泄電阻是非常重要的因素。pH計本質(zhì)上是一個高阻抗放大器，能夠準確測量微小的電極電壓，并直接在模擬或數(shù)字顯示器上顯示pH值測量結(jié)果。在某些情況下，可以讀取特殊應(yīng)用或者利用離子選擇或氧化還原電位（ORP）電極的電壓。pH電極在過去50到60年間，pH電極技術(shù)并未發(fā)生太大的改變。隨著過去30到40年的技術(shù)進步，pH電極制造仍然不失為一門藝術(shù)。電極的特制玻璃主體構(gòu)造是由玻璃吹制機吹制而成。上?？烧{(diào)PH計原電池的電動勢和氫離子濃度之間存在對應(yīng)關(guān)系，氫離子濃度的負對數(shù)即為pH值。</p><div

造成長久性堵塞。（二）使用一、pH計使用1.將電極從電極保護液中取出沖洗干凈，用無塵紙吸干后置于待測溶液中（待測液一定要沒過電極泡），按開機鍵打開pH計，pH計自動進入測定界面，然后按“measuresave/p”鍵，等待讀數(shù)穩(wěn)定后即可讀數(shù)。，將電極沖洗干凈用無塵紙吸干，充分浸泡電極保護液中。電極保護液要及時更換，一星期更換一次。二、pH計的校準1.將pH值分別為，，。2.按開機鍵打開pH計，將電極沖洗干凈用無塵紙吸干后置于pH為。按“calibrate”鍵到，等待讀數(shù)穩(wěn)定且讀數(shù)前面的光標閃爍時，按“數(shù)字編輯”鍵，調(diào)節(jié)pH計讀數(shù)到標準液的pH值。接著按“calibrate”鍵進入。3.將電極沖洗干凈用無塵紙吸干后置于pH為，等待讀數(shù)穩(wěn)定且讀數(shù)前面的光標閃爍時，按“數(shù)字編輯”鍵，調(diào)節(jié)pH計讀數(shù)到標準液的pH值。然后按“calibrate”鍵進入。4.將電極沖洗干凈用無塵紙吸干后置于pH為，等待讀數(shù)穩(wěn)定且讀數(shù)前面的光標閃爍時，按“數(shù)字編輯”鍵，調(diào)節(jié)pH計讀數(shù)到標準液的pH值。5.按“measuresave/p”鍵保存校正結(jié)果，得出三點校準后的直線斜率。若直線斜率在100±3范圍內(nèi)，且測定另外兩個標準緩沖液的pH值在±，則此次校準有效。否則需重新校準。酸度計的級別和儀器的準確度是不同的兩個概念，儀器級別與其準確度并不完全一致。</p><div
