氧氮氫分析儀的使用注意事項：1、氧氮氫分析儀在初次啟用前，應該對連接點、焊點、閥門等進行檢漏，以確?？諝庵械难醪粫礉B進入管道及儀器內(nèi)部，造成測量數(shù)值偏高。2、再次使用儀器前，要進行管道系統(tǒng)凈化，將漏入的空氣除干凈，同時確保連接取樣管路時沒有漏入空氣。3、樣氣中氧含量的變化會受管道材質(zhì)及表面粗糙度影響，因此一般連接管路選用銅管或拋光過的不銹鋼管，而不用塑料管、橡膠管等。4、微量元素分析時，要避免各種管件、閥門、表頭等死角對樣氣造成污染，因此必須盡可能的簡化氣路系統(tǒng)，連接件死角要小，以防止溶解氧逸出造成污染，使用水封、油封及臘封等設(shè)備，才能較好的確保數(shù)據(jù)的。上海禹重實業(yè)有限公司致力于提供分析儀，竭誠為您服務(wù)。江蘇美國LECO分析儀采購
