一氧化碳CO氣體判斷管106SH CARBON MONOXIDE 0.1%-2.0%

簡(jiǎn)要描述:

一氧化碳CO氣體測定管106SC CARBON MONOXIDE 1-50ppm,106SH CARBON MONOXIDE 0.1%-2.0%,一氧化碳CO氣體判斷管106SH CARBON MONOXIDE 0.1%-2.0%,由于 “氣味" 具有芳香(香味)和惡臭(臭味)等多種多樣的特征,所以很難用同一尺度進(jìn)行評價(jià)。因此,進(jìn)行氣味評價(jià)(量化)時(shí),需要在明確目的的基礎之上,選擇適當的評價(jià)方法。在此對惡臭的相關(guān)測定方法以及在企業(yè)等現場(chǎng)進(jìn)行自主管理時(shí)使用的簡(jiǎn)易測定方法,氣味傳感器(惡臭測試儀)
