水分測定儀的使用方法簡介

時間:2011/10/19閱讀:786
分享:
水分測定儀廣泛應用于一切需要快速測定水分的行業(yè),如醫(yī)藥,糧食、飼料、種子,菜籽,脫水蔬菜、煙草,化工,茶葉,食品、肉類以及紡織,農(nóng)林、造紙、橡膠、塑膠、紡織等行業(yè)中的實驗室與生產(chǎn)過程中。水分測定儀的使用方法<一.儀器自校,將主機后面板上的電源狀況顯示開路,測量數(shù)字將顯示zui大。顯示屏計數(shù)使陽極室電解液產(chǎn)生過量碘,此時應檢查下列情況: 1.測量插頭﹑插座是否接觸良好。2.測量電極引線是否開路,插頭焊接是否良好。二.電解開路,當電解開路時,電解曲線沒有。顯示屏不計數(shù)。此時應檢查下列情況1.電解插頭﹑插座是否接觸良好。2.陰極室上的電解引線是否開路,插頭焊接是否良好(當重新焊接插頭時,應注意陰﹑陽極性不得焊錯)。3.陰﹑陽電極鉑金絲的焊接點是否開路。三.測量短路,當測量短路時,狀態(tài)顯示過碘,數(shù)字顯示器不計數(shù),此時應檢查下列情況:1.測量插頭或插座是否短路。2.測量電極兩球端是否碰到一起或內(nèi)部是否短路。3.測量電極是否滲漏,滲漏時儀器滴定時間盡管超過半個小時以上,也不能到達終點(此時不屬于電解液問題,應更換測量電極)。
