這并非特別先進(jìn)的“高科技”過(guò)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(guò)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(lái)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
