則需要、、。校正順序根據(jù)不同儀器情況也各有區(qū)別，有的要求按順序校準，有的則沒有要求，儀器會自動識別，需要參見相關儀器使用說明書。2、不管是什么樣的pH計，pH=7這個點是必須校正的，而且在兩點校正的時候要先校正pH=7這個點。做校正時從，選擇的標準液與要測定的溶液的PH值有關，使溶液的PH值能落在校正的PH范圍內(nèi)。一般采用兩點就可以滿足要求，如果對其要求很高，才考慮第三點的。有些儀器能校正三點，有模式可選，可直接用該模式。有些沒有的，一般是采用兩點兩點校對，即校對兩次。3、我們通常用的是7，4，10的校準次序。先校酸后校堿。那么閑置了很久的PH計，而且電極也沒放在保護液里，要怎樣活化電極以及校正？需要注意些什么？標準校正液要怎么配？使用PH計要注意些什么細節(jié)呢？（一）保養(yǎng)1、pH玻璃電極的貯存短期：貯存在pH=4的緩沖溶液中；長期：貯存在pH=7的緩沖溶液中。2、pH玻璃電極的清洗玻璃電極球泡受污染可能使電極響應時間加長?？蒷4或皂液揩去污物，然后浸入蒸餾水一晝夜后繼續(xù)使用。污染嚴重時，可用5%HF溶液浸10～20分鐘，立即用水沖洗干凈，然后浸入HCl溶液一晝夜后繼續(xù)使用。3、玻璃電極老化的處理玻璃電極的老化與膠層結構漸進變化有關。土壤pH值是土壤重要的基本性質(zhì)之一。天津智能VOCPH計</p><p
