工業PH復合(he)電(dian)(dian)極(ji)(ji)前段(duan)的(de)保(bao)護瓶(ping)內(nei)(nei)有適(shi)量(liang)(liang)電(dian)(dian)極(ji)(ji)浸(jin)泡(pao)溶(rong)液(ye)(ye)(ye)，電(dian)(dian)極(ji)(ji)頭浸(jin)泡(pao)其中(zhong)，以保(bao)持玻璃球泡(pao)和液(ye)(ye)(ye)接界的(de)活化，測量(liang)(liang)時(shi)旋松瓶(ping)蓋(gai)，拔出電(dian)(dian)極(ji)(ji)，用(yong)(yong)(yong)去(qu)離子水洗凈即可使用(yong)(yong)(yong)。測量(liang)(liang)前，應注意將(jiang)玻璃泡(pao)內(nei)(nei)氣(qi)泡(pao)甩去(qu)，否則將(jiang)造成(cheng)測量(liang)(liang)誤(wu)差，測量(liang)(liang)時(shi)應將(jiang)電(dian)(dian)極(ji)(ji)在(zai)測試溶(rong)液(ye)(ye)(ye)中(zhong)攪動后靜(jing)止放置，以加速響應。檢查接頭處是否干(gan)燥清潔，如有沾污(wu)，需要用(yong)(yong)(yong)*擦洗干(gan)凈吹干(gan)后使用(yong)(yong)(yong)。建議采用(yong)(yong)(yong)二點法校準電(dian)(dian)極(ji)(ji)，通常先用(yong)(yong)(yong)PH6.86緩沖液(ye)(ye)(ye)校定位，再用(yong)(yong)(yong)PH4.01或PH9.18緩沖液(ye)(ye)(ye)確定斜(xie)率。用(yong)(yong)(yong)后再將(jiang)電(dian)(dian)極(ji)(ji)插進(jin)保(bao)護瓶(ping)并(bing)旋緊瓶(ping)蓋(gai)，經(jing)防止溶(rong)液(ye)(ye)(ye)滲出。電(dian)(dian)極(ji)(ji)應定時(shi)清洗若電(dian)(dian)極(ji)(ji)玻璃球泡(pao)與聚四氟乙(yi)烯環(huan)形液(ye)(ye)(ye)接界污(wu)染，可以用(yong)(yong)(yong)以下的(de)方法進(jin)行清洗：*、表面活性劑；第(di)二、鈣(gai)沉淀(dian)物(wu)或金屬氫氧化物(wu)可用(yong)(yong)(yong)10%的(de)稀鹽酸清洗；第(di)三、硫(liu)化物(wu)沉淀(dian)可用(yong)(yong)(yong)10%的(de)稀鹽酸清洗；第(di)四、蛋白(bai)質復合(he)物(wu)可用(yong)(yong)(yong)10%的(de)稀鹽酸和胃蛋白(bai)酶的(de)混(hun)合(he)物(wu)進(jin)行清洗。
