1915漢普儀 純氧分析器 實驗室玻璃儀器，固體吸收器概述及用途：

漢(han)普儀，1915漢(han)普儀（純氧分(fen)(fen)析(xi)器），也叫漢(han)氏氣體(ti)分(fen)(fen)析(xi)器：漢(han)普儀是用硼硅玻璃(li)經爐工和燈工精(jing)心焊接而(er)成。做工考究，制(zhi)作精(jing)良，經濟(ji)實(shi)用。

使用時需要裝(zhuang)置(zhi)在特制木架上。漢氏氣(qi)(qi)(qi)體(ti)分析器適應氣(qi)(qi)(qi)體(ti)分析的固體(ti)吸收，廣泛應用于制氧設備(bei)對氧氣(qi)(qi)(qi)和氮氣(qi)(qi)(qi)的純度試驗。

1915純氧分析器(qi)造型及(ji)原理：

漢普儀造型及原理:漢普儀是用硼硅玻璃經爐工和燈工精心焊接而成。漢普儀的結構是由一個圓形吸收球與一個圓形球焊接而成，在吸收球的下端有一個開口，便于放入固體吸收器或填料，然后用膠塞塞住，其上端接一只毛細管，是接氣體量管用。
