環(huán)己胺C6H11NH2氣體檢測管 105SD CYCLOHEXYL AMINE 1-20ppm

簡(jiǎn)要描述:

環(huán)己胺C6H11NH2 105SD CYCLOHEXYL AMINE (+) Cyclohexylamine 1-20ppm 因此,檢測管變色層的長(cháng)度和氣體的濃度成正比關(guān)系,觀(guān)察變色長(cháng)度就能檢測出空氣中目標氣體的濃度。隨時(shí)間的推進(jìn),氧氣分子進(jìn)入檢測劑的空隙和檢測劑接觸,并且越來(lái)越深入檢測管。這個(gè)過(guò)程持續推進(jìn),一層一層推進(jìn),直至沒(méi)有氧氣進(jìn)入,顏色變化停止。
