1,4-二氧六環(huán)氣體檢測(cè)管119U 1,4-DIOXANE 20-500ppm

簡(jiǎn)要描述:

1,4-二氧六環(huán) 119U 1,4-DIOXANE (+) 1,4-二堊烷檢測(cè)管,20-500ppm 1,4-二氧六環(huán)氣體檢測(cè)管119U 1,4-DIOXANE 20-500ppm,管道中氣流的流向及流速的檢測(cè)方法:發(fā)煙管作為氣體檢測(cè)的輔助工具,是用來測(cè)定管道中氣流的流向及流速的,管子里填充了容易發(fā)煙的物質(zhì)氯化錫。發(fā)煙管可重復(fù)使用,每次待測(cè)完畢后,用所附的橡膠帽蓋上即可。
