pH值的測(cè)量pH試紙或指示劑會(huì)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(zhǔn)確度上存在一定限制，難以通過(guò)顏色或模糊的樣本正確指示pH值。“pH”一詞**什么意思？術(shù)語(yǔ)pH中的“p”來(lái)源于表示負(fù)對(duì)數(shù)的數(shù)學(xué)符號(hào)“p”，而“H”來(lái)源于氫元素的化學(xué)符號(hào)。更準(zhǔn)確的測(cè)量需要采用pH計(jì)來(lái)完成。pH測(cè)量系統(tǒng)由三部分組成：pH測(cè)量電極，參比電極和高輸入阻抗計(jì)。pH電極可當(dāng)做一個(gè)電池，其電壓會(huì)隨著被測(cè)溶液的pH值變化而變化。pH值測(cè)量電極是一個(gè)對(duì)氫離子敏感的玻璃球，其毫伏級(jí)的輸出會(huì)隨著玻璃球內(nèi)外的相對(duì)氫離子濃度變化而發(fā)生改變。而參考電極的輸出并不會(huì)因?yàn)闅潆x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(cè)量pH值所導(dǎo)致的電壓變化。所以，pH計(jì)的輸入阻抗和漏泄電阻是非常重要的因素。pH計(jì)本質(zhì)上是一個(gè)高阻抗放大器，能夠準(zhǔn)確測(cè)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(cè)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(guò)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(guò)去30到40年的技術(shù)進(jìn)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(jī)吹制而成。北京PH計(jì)服務(wù)價(jià)格</p><p
