全自動工業分析儀是一(yi)種(zhong)工業用儀器(qi)。用來測(ce)試水分、灰分、揮發分三種(zhong)指標。

由分析儀、計算機系統、打印機三部分組成。其將遠紅外加熱設備與電子天平結合(he)在(zai)一(yi)起，在(zai)特定的(de)氣氛條件、規定的(de)時間內對受熱過(guo)程中的(de)試樣予以稱(cheng)重，以此(ci)計(ji)算(suan)出試樣的(de)水分(fen)、灰(hui)分(fen)及揮發分(fen)等工業分(fen)析指(zhi)標。實現水分(fen)、灰(hui)分(fen)、揮發分(fen)三項指(zhi)標間任意組合(he)測(ce)定或單獨測(ce)定，在(zai)150分(fen)鐘(zhong)內可以測(ce)試19個樣品的(de)水分(fen)、灰(hui)分(fen)、揮發分(fen)三項指(zhi)標。
