盡管ph計(jì)的種類(lèi)很多，但是校準(zhǔn)的方法無(wú)外乎就是三種，這篇文章介紹了一下ph計(jì)的三種方法以及ph計(jì)校準(zhǔn)三點(diǎn)校準(zhǔn)步驟教程，具體的一起來(lái)了解一下。ph計(jì)校準(zhǔn)的三種方法一、ph計(jì)的一點(diǎn)校準(zhǔn)任何一種pH計(jì)都必須經(jīng)過(guò)pH標(biāo)準(zhǔn)溶液的校準(zhǔn)后才可測(cè)量樣品的pH值，內(nèi)蒙古PH計(jì)認(rèn)真負(fù)責(zé)，對(duì)于測(cè)量精度在的樣品，可以采用一點(diǎn)極準(zhǔn)方法調(diào)整儀器，一般選用。有些儀器本身精度只有，因此儀器只設(shè)有一個(gè)¨定位¨調(diào)節(jié)旋鈕。具體操作步驟如下：（1）測(cè)量標(biāo)準(zhǔn)緩沖液溫度，查表確定該溫度下的pHs值，將溫度補(bǔ)償旋鈕調(diào)節(jié)到該溫度下，內(nèi)蒙古PH計(jì)認(rèn)真負(fù)責(zé)。（2）用純水沖洗電極并甩干。（3）將電極浸入緩沖溶液晃動(dòng)后靜止放置，待讀數(shù)穩(wěn)定后，調(diào)節(jié)定位旋鈕使儀器顯示該標(biāo)準(zhǔn)溶液的pH值。（4）取出電極沖洗并甩干。（5）測(cè)量樣品溫度，并將pH計(jì)溫度補(bǔ)償旋鈕調(diào)節(jié)至該溫度值二、ph計(jì)的二點(diǎn)校準(zhǔn)對(duì)于精密級(jí)的pH計(jì)，除了設(shè)有¨定位¨和¨溫度補(bǔ)償¨調(diào)節(jié)外，還設(shè)有電極¨斜率¨調(diào)節(jié)，它就需要用二種標(biāo)準(zhǔn)緩沖液進(jìn)行校準(zhǔn)。一般先以¨定位¨校準(zhǔn)，然后根據(jù)測(cè)試溶液的酸堿情況，選用（酸性）或（堿性）緩沖溶液進(jìn)行¨斜率¨校正。具體操作步驟為：（1）電極洗凈并甩干，浸入，儀器溫度補(bǔ)償旋鈕置于溶液溫度處，內(nèi)蒙古PH計(jì)認(rèn)真負(fù)責(zé)。待示值穩(wěn)定后。。表1的數(shù)據(jù)是精度為0.01級(jí)、經(jīng)過(guò)計(jì)量檢定合格的pH計(jì)在未校準(zhǔn)時(shí)與校準(zhǔn)后的測(cè)量值，可以看出校準(zhǔn)的重要性。內(nèi)蒙古PH計(jì)認(rèn)真負(fù)責(zé)</p><div

舊電極響應(yīng)遲緩，膜電阻高，斜率低。用氫氟酸浸蝕掉外層膠層，經(jīng)常能改善電極性能。若能用此法定期***內(nèi)外層膠層，則電極的壽命幾乎是無(wú)限的。4、參比電極的貯存銀-氯化銀電極比較好的貯存液是飽和氯化鉀溶液，高濃度氯化鉀溶液可以防止氯化銀在液接界處沉淀，并維持液接界處于工作狀態(tài)。此方法也適用于復(fù)合電極的貯存。5、參比電極的再生參比電極發(fā)生的問(wèn)題絕大多數(shù)是由液接界堵塞引起的，可用下列方法解決：（1）浸泡液接界：用10%飽和氯化鉀溶液和90%蒸餾水的混合液，加熱至60～70℃，將電極浸入約5cm，浸泡20分鐘至1小時(shí)。此法可溶去電極端部的結(jié)晶。（2）氨浸泡：當(dāng)液接界被氯化銀堵塞時(shí)可用濃氨水浸除。具體方法是將電極內(nèi)充洗凈，液放空后浸入氨水中10～20分鐘，但不要讓氨水進(jìn)入電極內(nèi)部。取出電極用蒸餾水洗凈，重新加入內(nèi)充液后繼續(xù)使用。（3）真空方法：將軟管套住參比電極液接界，使用水流吸氣泵，抽吸部分內(nèi)充液穿過(guò)液接界，除去機(jī)械堵塞物。（4）煮沸液接界：銀-氯化銀參比電極的液接界浸入沸水中10～20秒。注意，下一次煮沸前，應(yīng)將電極冷卻到室溫。（5）當(dāng)以上方法均無(wú)效時(shí)，可采用砂紙研磨的機(jī)械方法去除堵塞。此法可能會(huì)使研磨下的砂粒塞入液接界。山東官方PH計(jì)便攜式和臺(tái)式pH計(jì)測(cè)量范圍較廣，常用儀器，不同點(diǎn)是便攜式采用直流供電，可攜帶到現(xiàn)場(chǎng)。</p><div

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(zhǔn)，有的則沒(méi)有要求，儀器會(huì)自動(dòng)識(shí)別，需要參見(jiàn)相關(guān)儀器使用說(shuō)明書(shū)。2、不管是什么樣的pH計(jì)，pH=7這個(gè)點(diǎn)是必須校正的，而且在兩點(diǎn)校正的時(shí)候要先校正pH=7這個(gè)點(diǎn)。做校正時(shí)從，選擇的標(biāo)準(zhǔn)液與要測(cè)定的溶液的PH值有關(guān)，使溶液的PH值能落在校正的PH范圍內(nèi)。一般采用兩點(diǎn)就可以滿(mǎn)足要求，如果對(duì)其要求很高，才考慮第三點(diǎn)的。有些儀器能校正三點(diǎn)，有模式可選，可直接用該模式。有些沒(méi)有的，一般是采用兩點(diǎn)兩點(diǎn)校對(duì)，即校對(duì)兩次。3、我們通常用的是7，4，10的校準(zhǔn)次序。先校酸后校堿。那么閑置了很久的PH計(jì)，而且電極也沒(méi)放在保護(hù)液里，要怎樣活化電極以及校正？需要注意些什么？標(biāo)準(zhǔn)校正液要怎么配？使用PH計(jì)要注意些什么細(xì)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(zhǎng)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(yīng)時(shí)間加長(zhǎng)?？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(yán)重時(shí)，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(jié)構(gòu)漸進(jìn)變化有關(guān)。</p><p>
