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(zhǔn)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。“pH”一詞**什么意思？術(shù)語pH中的“p”來源于表示負(fù)對數(shù)的數(shù)學(xué)符號“p”，而“H”來源于氫元素的化學(xué)符號。更準(zhǔn)確的測量需要采用pH計(jì)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(jì)。pH電極可當(dāng)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?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，因此難以測量pH值所導(dǎo)致的電壓變化。所以，江蘇官方PH計(jì)源頭直供廠家，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)上是一個高阻抗放大器，能夠準(zhǔn)確測量微小的電極電壓，江蘇官方PH計(jì)源頭直供廠家，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(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。例如：分度為0.1pH的儀器稱為0.1級儀器;**小顯示值為0，江蘇官方PH計(jì)源頭直供廠家.001pH的儀器稱為0.001級儀器，等等。江蘇官方PH計(jì)源頭直供廠家</p><div
