盡管ph計的種類很多，但是校準的方法無外乎就是三種，這篇文章介紹了一下ph計的三種方法以及ph計校準三點校準步驟教程，具體的一起來了解一下。ph計校準的三種方法一、ph計的一點校準任何一種pH計都必須經過pH標準溶液的校準后才可測量樣品的pH值，對于測量精度在的樣品，可以采用一點極準方法調整儀器，一般選用。有些儀器本身精度只有，因此儀器只設有一個¨定位¨調節(jié)旋鈕。具體操作步驟如下：（1）測量標準緩沖液溫度，查表確定該溫度下的pHs值，將溫度補償旋鈕調節(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后靜止放置，待讀數穩(wěn)定后，調節(jié)定位旋鈕使儀器顯示該標準溶液的pH值。（4）取出電極沖洗并甩干。（5）測量樣品溫度，并將pH計溫度補償旋鈕調節(jié)至該溫度值二、ph計的二點校準對于精密級的pH計，除了設有¨定位¨和¨溫度補償¨調節(jié)外，還設有電極¨斜率¨調節(jié)，它就需要用二種標準緩沖液進行校準。一般先以¨定位¨校準，然后根據測試溶液的酸堿情況，選用（酸性）或（堿性）緩沖溶液進行¨斜率¨校正。具體操作步驟為：（1）電極洗凈并甩干，浸入，儀器溫度補償旋鈕置于溶液溫度處。待示值穩(wěn)定后。浙江智能PH計便宜</p><p
