概述
河南(nan)邦信(xin)陰極(ji)(ji)保護參比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)是測量各種電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)時作為(wei)參照(zhao)比(bi)較的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。將被測定的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)與(yu)已(yi)知電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)數值的(de)參比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)構成電(dian)(dian)(dian)(dian)(dian)(dian)池，測定電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)動勢(shi)數值，就可計(ji)算(suan)出(chu)被測定電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)。參比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)是電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)反(fan)應為(wei)單一的(de)可逆反(fan)應，電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)穩定和重(zhong)現性好。通常多用微溶(rong)鹽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)作為(wei)參比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)，氫電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)只是一個理想(xiang)的(de)但不(bu)易于實現的(de)參比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。
河南邦(bang)信常(chang)用參比電極種類：
氫電極用鍍有鉑黑的鉑片為電極材料，在氫氣氛中浸沒或部分浸沒于用氫飽和的電解液中，即可組成氫電極。
