這并非特別先進(jìn)的“高科技”過程，而是電極制造中非常關(guān)鍵且重要的一步。事實(shí)上，玻璃厚度決定了其電阻，進(jìn)而影響其輸出。溫度補(bǔ)償由于pH電極和pH測(cè)量均對(duì)溫度敏感，因此儀器設(shè)有溫度補(bǔ)償功能。溫度可通過手動(dòng)或自動(dòng)方式進(jìn)行補(bǔ)償。手動(dòng)補(bǔ)償功能需要單獨(dú)測(cè)量溫度值，可采用近似溫度值來設(shè)置pH計(jì)的手動(dòng)補(bǔ)償溫度。在自動(dòng)補(bǔ)償（ATC）設(shè)置中，單獨(dú)溫度探頭中的信號(hào)會(huì)傳輸至pH計(jì)，因此能準(zhǔn)確地確定樣本在該溫度下的pH值。緩沖溶液緩沖溶液是指具有恒定pH值且能夠避免pH值大幅度變化的溶液。緩沖溶液通常用于校準(zhǔn)pH測(cè)量系統(tǒng)（電極和測(cè)量計(jì)）。兩個(gè)電極的輸出之間可能存在微小差異，而且電極輸出隨著時(shí)間推移也會(huì)產(chǎn)生變化。因此，必須定期校準(zhǔn)pH測(cè)量系統(tǒng)。緩沖溶液適用于各種pH值，它們既可以是預(yù)混合的液體，也可以是方便使用的干粉膠囊。大多數(shù)pH計(jì)需要針對(duì)數(shù)個(gè)pH值進(jìn)行校準(zhǔn)。***個(gè)校準(zhǔn)數(shù)值通常是在等電位點(diǎn)（電極在pH7，25℃條件下所產(chǎn)生的信號(hào)為0mV）附近，第二個(gè)校準(zhǔn)數(shù)值通常是pH4或pH10。比較好選擇盡可能接近被測(cè)樣本實(shí)際pH值的緩沖溶液。</p><p> 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)。按便攜性分的，分為：便攜式pH計(jì)，臺(tái)式pH計(jì)和筆式pH計(jì)。</p><div
