盡管ph計(jì)的種類很多，但是校準(zhǔn)的方法無外乎就是三種，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pH標(biāo)準(zhǔn)溶液的校準(zhǔn)后才可測(cè)量樣品的pH值，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。（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。待示值穩(wěn)定后。環(huán)境監(jiān)測(cè)用便攜式PH計(jì)。</p><div
