酒精(乙醇)C2H5OH氣體檢測管104SA ETHYL ALCOHOL(ETHANOL)

簡要描述:

酒精(乙醇)C2H5OH氣體檢測管104SA ETHYL ALCOHOL(ETHANOL)0.05-5.0%,當(dāng)被測氣體中含有硫化氫通過檢測管時,與吸附在載體上的醋酸鉛產(chǎn)生棕褐色染色段,染色段長度與硫化氫含量成正比例,測定不同氣體的檢測管其化學(xué)組成是不同的,檢測管的化學(xué)反應(yīng)原理與常用的化學(xué)分析反應(yīng)原理基本相同,檢測管法只是將化學(xué)分析中的所謂“液態(tài)反應(yīng)"轉(zhuǎn)移到固體表面上進行的。
