造成長(zhǎng)久性堵塞。（二）使用一、pH計(jì)使用1.將電極從電極保護(hù)液中取出沖洗干凈，用無塵紙吸干后置于待測(cè)溶液中（待測(cè)液一定要沒過電極泡），按開機(jī)鍵打開pH計(jì)，pH計(jì)自動(dòng)進(jìn)入測(cè)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(hù)液中。電極保護(hù)液要及時(shí)更換，一星期更換一次。二、pH計(jì)的校準(zhǔn)1.將pH值分別為，，。2.按開機(jī)鍵打開pH計(jì)，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(biāo)閃爍時(shí)，按“數(shù)字編輯”鍵，調(diào)節(jié)pH計(jì)讀數(shù)到標(biāo)準(zhǔn)液的pH值。接著按“calibrate”鍵進(jìn)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(biāo)閃爍時(shí)，按“數(shù)字編輯”鍵，調(diào)節(jié)pH計(jì)讀數(shù)到標(biāo)準(zhǔn)液的pH值。然后按“calibrate”鍵進(jìn)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(biāo)閃爍時(shí)，按“數(shù)字編輯”鍵，調(diào)節(jié)pH計(jì)讀數(shù)到標(biāo)準(zhǔn)液的pH值。5.按“measuresave/p”鍵保存校正結(jié)果，得出三點(diǎn)校準(zhǔn)后的直線斜率。若直線斜率在100±3范圍內(nèi)，且測(cè)定另外兩個(gè)標(biāo)準(zhǔn)緩沖液的pH值在±，則此次校準(zhǔn)有效。否則需重新校準(zhǔn)。</p></p><br
